Hebrews 11:9, 12

He lived by faith as an immigrant in his promised land as though it belonged to someone else. He journeyed through the land living in tents with Isaac and Jacob who were persuaded that they were also co-heirs of the same promise.

In fact, so many children were subsequently fathered by this aged man of faith—one who was as good as dead, that he now has offspring as innumerable as the sand on the seashore and as the stars in the sky!
