Who is God/Elohim in the Bible?

"Moses said to God, “Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ Then what shall I tell them?” Exe 3:13

"God said to Moses, “I am who I am. This is what you are to say to the Israelites: ‘I am sent me to you.’ ” Exe 3:15

When God speaks of his own name, he says:

EH·WEH - I am who I am

The letters EH represent the word I.

When we speak God's name, we say He, which is the Hebrew word YA. Therefore we say, "He is" when saying the name of God YA-WEH. Only Elohim can say EH-WEH, for it means "I am."

"God also said to Moses, “Say to the Israelites, ‘The Lord (YA-WEH), the God of your fathers—the God of Abraham, the God of Isaac and the God of Jacob—has sent me to you." Ex 3:15

Moses didn't go to the Israelites and say, "I am sent me." He, in fact, said, "He is has sent me."
