Hebrews 11:15 (KJV)

For he looked for a city which hath foundations, whose builder and maker is God.

Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised.

Therefore sprang there even of one, and him as good as dead, so many as the stars of the sky 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 afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth.

For they that say such things declare plainly that they seek a country.

But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.

By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,

Of whom it was said, That in Isaac shall thy seed be called:

Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.

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