17By faith cAbraham, 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, dThrough Isaac shall your offspring be named.” 19 eHe considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back.
