Genesis 22:9-12

LXX2012(i) 9 came to the place which God spoke of to him; and there Abraam built the altar, and laid the wood on it, and having bound the feet of Isaac his son together, he laid him on the altar upon the wood. 10 And Abraam stretched forth his hand to take the knife to kill his son. 11 And an angel of the Lord called him out of heaven, and said, Abraam, Abraam. And he said, Behold, I [am here]. 12 And he said, Lay not your hand upon the child, neither do anything to him, for now I know that you fear God, and for my sake you have not spared your beloved son.
