Genesis 22:5

5 Abraham said to his young men, "Stay here with the donkey. The boy and I will go yonder. We will worship, and come back to you. 

Hebrews 11:17-19

17 By faith, Abraham, being tested, offered up Isaac. Yes, he who had gladly received the promises was offering up his one and only son;  18 even he to whom it was said, "In Isaac will your seed be called;"  19 accounting that God is able to raise up even from the dead. Figuratively speaking, he also did receive him back from the dead.
