And so, having patiently waited, he realized the promise [in the miraculous birth of Isaac, as a pledge of what was to come from God].

By faith, he lived as a foreigner in the land of promise, as in a land not his own, dwelling in tents, with Isaac and Jacob, the heirs with him of the same promise.

But the truth is that they were longing for a better country, that is, a heavenly one. For that reason God is not ashamed [of them or] to be called their God [even to be surnamed their God—the God of Abraham, Isaac, and Jacob]; for He has prepared a city for them.

By faith, Abraham, being tested, offered up Isaac. Yes, he who had gladly received the promises was offering up his one and only son;

even he to whom it was said, "In Isaac will your seed be called;"

Abraham was certain that God could raise the dead, and figuratively speaking, he did get Isaac back in this way.

By faith, Isaac blessed Jacob and Esau, even concerning things to come.

for you know that afterward, when he would have inherited the blessing, he was rejected: not being able to make Isaac to retract, though he importun'd him with tears.
