Hebrews 11:8-10

By faith Abraham, when he was called, obeyed to go out unto a place which he was to receive for an inheritance; and he went out, not knowing whither he went.

By faith he became a sojourner in the land of promise, as in a land not his own, dwelling in tents, with Isaac and Jacob, the heirs with him of the same promise:

for he looked for the city which hath the foundations, whose builder and maker is God.
