Genesis 22:9
8 “God will provide for himself the lamb for the burnt offering, my son,” Abraham replied. The two of them continued on together. 9 When they came to the place God had told him about, Abraham built the altar there and arranged the wood on it. Next he tied up his son Isaac and placed him on the altar on top of the wood. 10 Then Abraham reached out his hand, took the knife, and prepared to slaughter his son. 11 But the angel of the Lord called to him from heaven, “Abraham! Abraham!” “Here I am!” he answered.
1 Kings 13:2
1 Just then a prophet arrived from Judah with the Lord’s message for Bethel, as Jeroboam was standing near the altar ready to offer a sacrifice. 2 He cried out against the altar with the Lord’s message, “O altar, altar! This is what the Lord has said, ‘Look, a son named Josiah will be born to the Davidic dynasty. He will sacrifice on you the priests of the high places who offer sacrifices on you. Human bones will be burned on you.’” 3 That day he had also given a sign, saying, “This is the sign that the Lord has declared: The altar will split open and the ashes on it will pour out.”
Notes and References
"... The only contexts in which the expression can be rendered, 'you will slaughter on it' involve human victims (compare 1 Kings 13:2; 2 Kings 23:20). In the 'Binding of Isaac,' Abraham builds an altar, stacks a pyre, trusses Isaac, and deposits him on top of the wood where he intends to slaughter him (Genesis 22:9-10). On the strength of the presupposition of this particular story, namely, that such a procedure is precedented, allowance must be made that slaughter on the altar itself was perceived as acceptable with certain types of altars and certain types of sacrifices ..."
