Genesis 22:1-2

Young's Literal Translation

22 And it cometh to pass after these things that God hath tried Abraham, and saith unto him, `Abraham;' and he saith, `Here [am] I.'

² And He saith, `Take, I pray thee, thy son, thine only one, whom thou hast loved, even Isaac, and go for thyself unto the land of Moriah, and cause him to ascend there for a burnt-offering on one of the mountains of which I speak unto thee.'
