Genesis 22:8-10 New Revised Standard Version, Anglicised Catholic Edition (NRSVACE)
8 Abraham said, ‘God himself will provide the lamb for a burnt-offering, my son.’ So the two of them walked on together.
9 When they came to the place that God had shown him, Abraham built an altar there and laid the wood in order. He bound his son Isaac, and laid him on the altar, on top of the wood. 10 Then Abraham reached out his hand and took the knife to kill[a] his son.
