In Genesis 24, Abraham tells his servant to go back to his homeland and find a wife for Isaac from Abraham's country and Abraham's relatives.

First of all, I suppose I can understand why Isaac was not allowed to marry a Canaanite. Abraham didn't want Isaac, the son of promise, to be led astray by a wife outside the covenant, right?

But that still doesn't explain why the wife had to come from within Abraham's relatives. Sure, the servant could go back to his hometown; but surely there were other eligible young women among other families?

  • It was very typical in ancient times to marry cousins. But since Abraham is seemingly the first monotheist in this era, it would seem the only other choice would be to marry one of Abraham's slaves, and children of slave wives would not inherit. Jan 2, 2015 at 20:57

Why intermarriage with Canaanites was forbidden

It says in Exodus:

Observe what I command you today. See, I will drive out before you the Amorites, the Canaanites, the Hittites, the Perizzites, the Hivites, and the Jebusites. Take care not to make a covenant with the inhabitants of the land to which you are going, or it will become a snare among you. You shall tear down their altars, break their pillars, and cut down their sacred poles (for you shall worship no other god, because the Lord, whose name is Jealous, is a jealous God). You shall not make a covenant with the inhabitants of the land, for when they prostitute themselves to their gods and sacrifice to their gods, someone among them will invite you, and you will eat of the sacrifice. And you will take wives from among their daughters for your sons, and their daughters who prostitute themselves to their gods will make your sons also prostitute themselves to their gods. (Exodus 34:11–16, emphasis added)

And again in Deuteronomy:

When the Lord your God brings you into the land that you are about to enter and occupy, and he clears away many nations before you—the Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, seven nations mightier and more numerous than you—and when the Lord your God gives them over to you and you defeat them, then you must utterly destroy them. Make no covenant with them and show them no mercy. Do not intermarry with them, giving your daughters to their sons or taking their daughters for your sons, for that would turn away your children from following me, to serve other gods. Then the anger of the Lord would be kindled against you, and he would destroy you quickly. But this is how you must deal with them: break down their altars, smash their pillars, hew down their sacred poles, and burn their idols with fire. For you are a people holy to the Lord your God; the Lord your God has chosen you out of all the peoples on earth to be his people, his treasured possession. (Deuteronomy 7:1–6, emphasis added)

All of the seven nations listed except the Perizzites (whose origins are unknown) are descended from Canaan, son of Ham (see Genesis 10:15–19), who was cursed by Noah in the incident recorded in Genesis 9:20–27. This incident and curse on Canaan is the origin story for a lasting conflict between the Hebrew people, who were descendants of Shem, and the Canaanites, who occupied much of the Holy Land at the time Abraham, and later the Israelites, first entered it.

Aside from the implicit directive to avoid intermingling with the descendants of Canaan because they were seen as cursed, a more explicit reason for the prohibition on marrying them given in the above two quotations is that intermarriage with them would cause the Israelites to begin honoring and worshiping their gods, thus forsaking the God of Israel, who demanded their sole worship and obedience.

In a nutshell, then, the Hebrews, and later the Israelites, were forbidden to intermarry with the descendants of Canaan because:

  1. Canaan and his descendants were considered cursed.
  2. Intermarrying with them would cause them to become unfaithful to their God.

Abraham also wanted to avoid intermarrying with descendants of Canaan

Although the explicit commandment not to intermarry with the descendants of Canaan is recorded in the Bible narrative long after the time of Abraham, many of the commandments given to the Israelites after the exodus from Egypt were codifications of rules that had already long been in place. For example, the law of levirate marriage recorded in Deuteronomy 25:5–10 was already being observed much earlier, during the time of Judah (see Genesis 38:1–11).

We can therefore presume that even during the time of Abraham, intermarriage with descendants of Canaan was not acceptable for Hebrews such as Abraham. This is borne out in the opening lines of the story of Abraham sending his trusted servant to get a wife for his son Isaac:

Now Abraham was old, well advanced in years; and the Lord had blessed Abraham in all things. Abraham said to his servant, the oldest of his house, who had charge of all that he had, "Put your hand under my thigh and I will make you swear by the Lord, the God of heaven and earth, that you will not get a wife for my son from the daughters of the Canaanites, among whom I live, but will go to my country and to my kindred and get a wife for my son Isaac." (Genesis 24:1–4, emphasis added)

Here Abraham specifically mentions the Canaanites among whom he lives as not being suitable to provide a wife for his son Isaac. And though there were other, non-Canaanite nations in the region as well, they, too, would worship other gods, making it too risky to marry his son Isaac to one of their daughters. Instead, he chose to seek a wife for his son from among his own relatives.

The covenant with Abraham

Earlier in the Bible narrative, just before and just after the Great Flood, God had made a covenant with Noah, which would cover him, his descendants, and all living beings on earth. In this covenant, God promised never again to cause a flood that would destroy all living beings. See Genesis 6:18; 9:1-17.

Later, however, God made a more specific covenant with Abram, whom he renamed Abraham. This covenant is first recorded in Genesis 15, and repeated with further detail in Genesis 17. In this covenant, God promises to give to Abraham and to his descendants the land of Canaan. In return, Abraham, all of the males in his household, and all of his descendants and the males in their households must be circumcised as a sign of their covenant with God.

This more specific covenant did not apply to all of humankind, but only to Abraham and his descendants. Further, it did not even apply to all of Abraham's descendants, but only to his designated heir, Isaac, and Isaac's descendants:

And Abraham said to God, "O that Ishmael might live in your sight!" God said, "No, but your wife Sarah shall bear you a son, and you shall name him Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. As for Ishmael, I have heard you; I will bless him and make him fruitful and exceedingly numerous; he shall be the father of twelve princes, and I will make him a great nation. But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year." (Genesis 17:18–21, emphasis added)

This covenant, then, was very specific to Abraham and his designated heir Isaac, miraculously borne by Abraham's wife Sarah in her old age. Therefore a suitable wife for Isaac must not come from any of these other nations—even the non-Canaanite ones—but must come from as close to Abraham's own family line as possible.

Abraham therefore sent his trusted servant to his immediate relatives living north of the land of Canaan in Aram-naharaim, in the city where his brother Nahor had settled (see Genesis 11:27–32; 24:10). From there, as told in Genesis 24, Abraham's servant got as a wife for Isaac Rebekah, granddaughter of Abraham's brother Nahor, making her Isaac's first cousin once removed.


It looks like Nahor left Ur to join Abraham & Terah in Harran. His family would have known of the God of Abraham. That explained why Laban’s first word remarkably addressed Abraham’s servant as “one who is blessed by Yahweh” (Gen 24:31). And Laban attributed it to Yahweh who divinely directed the servant to find Rebekah as Isaac’s chosen wife (Gen 24:50). He did appear to know or believe in Yahweh. Later (Gen 30) we learned that he practiced divination & possessed “household” gods while still acknowledging the power of Abraham’s God. I can only gather that his monotheism was by no means pure. Looks like a human tendency to collect “gods” for more securities, believe in superstitions, fashioning for himself idols to protect his household.

As for Canaanites, it’s made known to Abraham that these nations are under God’s judgment/cursed due to their wickedness (Gen 15:14-16). It’s always God’s intention for Abraham to be set apart from the inhabitants of the land, which includes no intermarry covenant wt Canaanites. Not only for Abraham’s covenanted son Isaac but also for the whole nation of Israel (Deu 7:1–6). This explained why Isaac & Rebekah were disgusted wt living because of Esau’s Hittites wives.

Hence, a suitable wife for Isaac must not come from any of these nations, But the angel of God will go before his servant to find a suitable wife for Isaac from among his relatives (Gen 24:7).

And why not marry Ishmael’s descendants? As prophesied, Ishmael’s descendants lived in hostility towards all the tribes related to them. This includes an estranged relationship with Isaac’s covenanted line as God intended.

There is a linguistic explanation that fits well with the biblical accounts of the genealogies of the Hebrew patriarchs. We now know that the early Israelites were polytheistic and actually worshipped the moon god, among others - see for example, The Early History of God: Yahweh and the Other Deities in Ancient Israel, by Mark S. Smith.

We know that Isaac is not to marry any of the people he lives among, and we will also find that his son, Jacob, must be found a wife from within Abraham's family. Leon R. Kass points out, in The Beginning of Wisdom: Reading Genesis, at page 255, that when we eventually learn of Sarai’s parentage (Sarah was the daughter of Terah and sister of Abram), we will see how "the patriarchal family line is a self-contained unit, originating solely in Terah, with no pathways to or from the outer world." In other words, the patriarchs are to be descended on both their paternal and maternal sides from the one ancestor, Terah, father of Abraham.

The one explanation that arises from a reading of the Hebrew texts is that in ancient, pre-biblical traditions, Abraham, Isaac and Jacob might have been otherworldly people. Terah, and his son Abram, came from Ur and travelled to Haran, both principal cities of the moon god, Sin. The Hebrew root for the name Terah means either ‘moon’ or ‘month’, and in what is now northern Syria the name of the moon god was Terah.

Isaac could not marry any of the mortals in the land, so Abraham sent a servant to his former city of Haran to find a wife for Isaac. The servant found a young maiden at the nearby town of Nahor. Nahor, the name of the Abraham's brother, means 'Light' or 'Lamp', suggestive of the moon. Rebekah, the chosen wife, was the daughter of Bethuel and Milcah, which in Akkadian was a title given to Ishtar, the moon god's daughter. Also, Laban ('white' or 'bright') and each of Terah's other male descendants have names associated with the moon, while the names Rachel and Leah seem to be associated with the goddess Asherah, or Venus.

All this points to the possibility of an earlier, pre-biblical tradition that the patriarchs were incarnations of the moon god. As such, they could not marry ordinary humans.

  • gods married human women all the time in ancient pagan mythology, so even if the beginning of this argument could be proven somehow, the conclusion is totally faulty. Jan 2, 2015 at 20:58

    @davidbrainerd Every religion is different. I would not say that because I found a certain belief in Islam that Christians most certainly believe the same thing. I believe this comment is an example of looking for non-existent evidence to balance the evidence so clearly given. Jan 2, 2015 at 21:47
