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! (AMP)

And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. (KJV)
