By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went. Hebrews 11:8 (KJV)
"But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year" (Genesis 17:21).
"And Jacob vowed a vow, saying, If God will be with me, and will keep me in this way that I go, and will give me bread to eat, and raiment to put on" (Genesis 28:20).

"Know ye therefore that they which are of faith, the same are the children of Abraham. And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed. So then they which be of faith are blessed with faithful Abraham" (Galatians 3:7-9)
