Genesis 17:15

God said to Abraham, “As for your wife Sarai, do not call her Sarai, for Sarah will be her name.

Your name will no longer be Abram, but your name will be Abraham, for I will make you the father of many nations.

“Your name will no longer be Jacob,” He said. “It will be Israel because you have struggled with God and with men and have prevailed.”

and He sent a message through Nathan the prophet, who named him Jedidiah, because of the Lord.
