Hebrews 11:8-10

8 By faith Abraham, when he was called, obeyed by going out to a place which he was to receive for an inheritance; and he went out, not knowing where he was going. 9 By faith he lived as an alien in the land of promise, as in a foreign land, dwelling in tents with Isaac and Jacob, fellow heirs of the same promise; 10 for he was looking for the city which has foundations, whose architect and builder is God.
