It is written:
And when Abram was ninety nine years old, Yahu appeared to Abram.
And Yahu appeared to him (Abraham) in the plains of Mamre.
And it is written:
And Yahu said to Abraham, “Why did Sarah laugh?”
And Yehoshua said,
“Your father Abraham rejoiced to see my day, and he saw it, and was glad.”
Then the Yehudim said to him, “You are not yet fifty years old, and have you seen Abraham?”
Yehoshua said to them, “Amen, amen, I say to you: Before Abraham was, I AM.”
You believe in God.
