Hebrews 11:17-19

Revised Standard Version

¹⁷ By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was ready to offer up his only son, ¹⁸ of whom it was said, “Through Isaac shall your descendants be named.” ¹⁹ He considered that God was able to raise men even from the dead; hence, figuratively speaking, he did receive him back.
