Hebrews 11:7-12

By faith Noah, being warned by God about things not yet seen, in reverence prepared an ark for the salvation of his household, by which he condemned the world, and became an heir of the righteousness which is according to faith. 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. 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; for he was looking for the city which has foundations, whose architect and builder is God. By faith even Sarah herself received ability to conceive, even beyond the proper time of life, since she considered Him faithful who had promised. Therefore there was born even of one man, and him as good as dead at that, as many descendants AS THE STARS OF HEAVEN IN NUMBER, AND INNUMERABLE AS THE SAND WHICH IS BY THE SEASHORE.
