And I will make your descendants as the dust of the earth: so that if a man can number the dust
of the earth, then shall your descendants also be numbered.
All Commentaries on Genesis 13:16 Go To Genesis 13
John Chrysostom
AD 407
Then, in case Abraham should have regard only to his own condition, his advanced years and Sarah’s sterility, and thus lose confidence in the promise instead of trusting in the power of the One making the promise, he said, “I will make your descendants as numerous as all the grains of sand in the world. If anyone can number the grains of sand in the world, your descendants too will be numbered.” No doubt the promise went beyond human nature. Not only did he promise to make him a father despite so many impediments but also to extend the gift to such a multitude as to be compared with all the grains of sand in the world, and the multitude to be beyond number, wishing as he did to demonstrate the extent of the remarkable increase by the comparison.
