I am trying to find Moses’ age when he was standing before the Burning Bush before delivering the Israelites from slavery. Later in Scripture it says he was 80 years when he first spoke to Pharaoh. Does scripture give any idea how old he was before the Burning Bush, or he was also around 80 years old at that time?
Scripture tells us Moses was 40 when the Egyptian struck the slave: Acts 7:22-29
22 And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and in deeds. 23 And when he was full forty years old, it came into his heart to visit his brethren the children of Israel.
And then...in Acts 7:30
And when forty years were expired, there appeared to him in the wilderness of Mount Sinai an angel of the Lord in a flame of fire in a bush.
In Exodus 7:7, we see the age at which Moses (and Aaron) when they go to Pharaoh:
Moses was 80 years old and Aaron 83 when they spoke to Pharaoh..."
So Moses was 40 when he killed the Egyptian, and 80 at both the time of the Burning Bush and the meeting with Pharaoh.
He was about 80
The timeline would look like this:
0 - [Moses is born]
40 - Acts 7:23-24 ESV When he was forty years old, it came into his heart to visit his brothers, the children of Israel. And seeing one of them being wronged, he defended the oppressed man and avenged him by striking down the Egyptian.
80 - Acts 7:30 ESV Now when forty years had passed, an angel appeared to him in the wilderness of Mount Sinai, in a flame of fire in a bush.
80 - Exodus 7:3 ESV Now Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
>80 - Number 32:13 ESV And the Lord's anger was kindled against Israel, and he made them wander in the wilderness forty years, until all the generation that had done evil in the sight of the Lord was gone.
120 - [dead]
Moses 80 years old
Acts 7:23: "When Moses was 40 years old, he decided to visit his fellow Israelites. He saw one of them being mistreated by an Egyptian, so he went to his defense and avenged him by killing the Egyptian. Acts 7:30: "After forty years had passed [after Moses killed the Egyptian], an angel appeared to Moses in the flames of a burning bush in the desert near Mount Sinai. See Exodus 2:1-25. Notice in verses 22-23 that after Moses got married to Zipporah, he had a son (Gershom), and the king of Egypt died. Verse 23 says, "During that long period, the king of Egypt died. The Israelites groaned in their slavery and cried out, and their cry for help because of their slavery went up to God." He was 40 years old when he killed the Egyptian, and after a long period (marriage and the king died), he saw the burning bush. It seems to me that it would be correct to date Moses at 80 years of age when God called him (spoke to him) from the burning bush.
