The Lord prophesies Isaac's birth by the oaks of Mamre. (Genesis 18)
The Binding of Isaac
In response to God's test, Abraham cut wood for a burnt offering and departed for a place of which God shall tell him. When he spotted the place, Abraham took the wood and laid it on Isaac, while he took in his hand the fire and the knife. When they came to the place of which God had told Abraham, Abraham built the altar there and laid the wood in order and bound Isaac his son and laid him on the altar, on top of the wood. Then Abraham reached out with the knife to slaughter his son, but the angel of the Lord stopped him and reaffirmed the Abrahamic covenant for his obedience in not withholding even his only son.
