Genesis 22:10-12 New International Version - UK (NIVUK)
10 Then he reached out his hand and took the knife to slay his son. 11 But the angel of the Lord called out to him from heaven, ‘Abraham! Abraham!’
‘Here I am,’ he replied.
12 ‘Do not lay a hand on the boy,’ he said. ‘Do not do anything to him. Now I know that you fear God, because you have not withheld from me your son, your only son.’
