Hebrews 11:8-10

By faith Abraham, when he was called, obeyed and went out to a place he was going to receive as an inheritance. He went out, not knowing where he was going. By faith he stayed as a foreigner in the land of promise, living in tents with Isaac and Jacob, coheirs of the same promise. For he was looking forward to the city that has foundations, whose architect and builder is God.
