Moses' age when before the burning bush 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.
