Hebrews 11:17-21

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.

By faith Jacob, when he was a dying, blessed both the sons of Joseph; and worshipped, leaning upon the top of his staff.
