Hebrews 11:11-20

By faith even Sarah herself received power to conceive seed when she was past age, since she counted him faithful who had promised: wherefore also there sprang of one, and him as good as dead, so many as the stars of heaven in multitude, and as the sand, which is by the sea-shore, innumerable. These all died in faith, not having received the promises, but having seen them and greeted them from afar, and having confessed that they were strangers and pilgrims on the earth. For they that say such things make it manifest that they are seeking after a country of their own. And if indeed they had been mindful of that country from which they went out, they would have had opportunity to return. But now they desire a better country, that is, a heavenly: wherefore God is not ashamed of them, to be called their God; for he hath prepared for them a city. By faith Abraham, being tried, offered up Isaac: yea, he that had gladly received the promises was offering up his only begotten son; even he to whom it was said, In Isaac shall thy seed be called: accounting that God is able to raise up, even from the dead; from whence he did also in a figure receive him back. By faith Isaac blessed Jacob and Esau, even concerning things to come.
