And God said unto Moses,
I AM THAT I AM:
and he said,
Thus shall you say unto the children of Israel, I AM has sent me unto you.

So in Genesis [sic] he bade Moses say of himself, “Go and say to the children of Israel, I am who I am. He who is has sent me to you.” So he wanted his eternity to be denoted by the present tense. This use of present time (“today”) is acknowledged to be peculiar to the divine Scriptures in the sense of perpetuity.
