Hebrews 11:16-20
English Standard Version
17By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son,
18of whom it was said, "Through Isaac shall your offspring be named."
19He considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back.
20By faith Isaac invoked future blessings on Jacob and Esau.
