"Now the angel of the Lord came up from Gilgad to Bochim, And he said, "I brought you up out of Egypt and led you into the land which I have sworn to your fathers; and I said, I will never break My covenant with you." Then at Judges 2:5, "So they named that place Bochim and there they sacrificed to the Lord." Going back to Exodus 20:1-3, Then God spoke all these words, saying, Verse 2, I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery. Verse 3, "You shall have no other gods before Me."
The covenant referred to can be found at Genesis 17:1-7. "Now when Abram was ninety-nine years old, the Lord appeared to Abram and said to him, "I am God Almighty; Walk befor3e Me, and be blameless, verse 2, And I will establish My covenant between Me and you, And I will multiply you exceedingly." Verse 3, And Abram fell on his face, and God talked with him, saying, verse 4, As for Me, behold, My covenant is with you, And you shall be the father of a multitude of nations. verse 5, No longer shall your name be called Abram, But you name shall be Abraham; For I will make you the father of a multitude of nations.
Verse 6, And I will make you exceedingly fruitful, and I will make nations of you, and kings shall come forth from you. verse 7, And I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you."
This covenant is further amplified at Genesis 22 where the Lord tested Abraham to sacrifice his son Isaac. At Genesis 22:10 Abraham stretched out his hand, and took the knife to slay his son." Verse 11, BUT the angel of the Lord called to him from heaven, and said, "Abraham, Abraham!" And he said, Here I am." Verse 12, "Do not stretch out your hand against the lad, and do nothing to him; for now I know that you fear God, since you have not withheld your son, your only son from Me."
At verse 15, Then the angel of the Lord called to Abraham a second time from heaven, verse 16, and said, "By Myself I have sworn, declares the Lord because you have done this thing, and have not withheld your son, your only son, verse 17, indeed I will greatly multiply your seed as the stars of the heavens, and as the sand which is on the seashore; and your seed shall possess the gate of their enemies. Verse 18, And in your seed all the nations of the earth shall be blessed, because you have obeyed My voice."
The New Testament at Hebrews 6:13-16 clearly identifies and confirms who swore the oath. "For when God made the promise to Abraham, since He could swear by no one greater, He swore by Himself, verse 14, saying, "I will surely bless you, and I will surely multiply you." Notice what verse 16 states, "For men swear by one greater than themselves, and with them an oath give as confirmation is an end of every dispute. In taking oaths, men swear by God who is greater than they are. They do so in order to convince other men that they are truthful and intend to abide by their promises.
So getting back to the question? Why does Judges 2:1 say the angel of the Lord would never break his covenant he swore to the fathers?
