Hebrews 11:17-22

By faith Abraham, when he was tested [that is, as the testing of his faith was still in progress], offered up Isaac, and he who had received the promises [of God] was ready to sacrifice his only son [of promise]; [Gen 22:1-10] to whom it was said, “THROUGH ISAAC YOUR DESCENDANTS SHALL BE CALLED.” [Gen 21:12] For he considered [it reasonable to believe] that God was able to raise Isaac even from among the dead. [Indeed, in the sense that he was prepared to sacrifice Isaac in obedience to God] Abraham did receive him back [from the dead] figuratively speaking. By faith Isaac blessed Jacob and Esau [believing what God revealed to him], even regarding things to come. [Gen 27:27-29, 39, 40] By faith Jacob, as he was dying, blessed each of the sons of Joseph, and bowed in worship, leaning on the top of his staff. [Gen 48] By faith Joseph, when he was dying, referred to [the promise of God for] the exodus of the sons of Israel [from Egypt], and gave instructions concerning [the burial of] his bones [in the land of the promise]. [Gen 50:24, 25; Ex 13:19]
