By faith Abraham, when he was tested, 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 your descendants be called: Accounting that God was able to raise him up, even from the dead; from which also he received him in a figure. By faith Isaac blessed Jacob and Esau concerning things to come. By faith Jacob, when he was dying, blessed both the sons of Joseph; and worshiped, leaning upon the top of his staff. By faith Joseph, when he died, made mention of the departing of the children of Israel; and gave commandment concerning his bones. (Hebrews 11:17-22)
