Exodus 3:12-14

Amplified Bible, Classic Edition

¹² God said, I will surely be with you; and this shall be the sign to you that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain [Horeb, or Sinai].

¹³ And Moses said to God, Behold, when I come to the Israelites and say to them, The God of your fathers has sent me to you, and they say to me, What is His name? What shall I say to them?

¹⁴ And God said to Moses, I Am Who I Am and What I Am, and I Will Be What I Will Be; and He said, You shall say this to the Israelites: I Am has sent me to you!
