These all died in faith, not having received what was promised, but having seen it and greeted it from afar, and having acknowledged that they were strangers and exiles on the earth. For people who speak thus make it clear that they are seeking a homeland. If they had been thinking of that land from which they had gone out, they would have had opportunity to return. But as it is, they desire a better country, that is, a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared for them a city.
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, of whom it was said, “Through Isaac shall your descendants be named.” He considered that God was able to raise men even from the dead; hence, figuratively speaking, he did receive him back. By faith Isaac invoked future blessings on Jacob and Esau. By faith Jacob, when dying, blessed each of the sons of Joseph, bowing in worship over the head of his staff. By faith Joseph, at the end of his life, made mention of the exodus of the Israelites and gave directions concerning his burial.
–Hebrews 11:13-22
