Êxodo 3

13 Then Moses said to God: »Behold, I am going to the sons of Israel. I will say to them: The God of your fathers has sent me to you. Now they may ask me: What is His name? What shall I say to them?«

14 God then said to Moses: »I exist and I WILL BE WHO I WILL BE.« You shall say to the sons of Israel: »I WILL BE, has sent me to you.« Hebrew: hayah, »I was, I am, I will be« gives evidence of Gods eternal existence
