John Wesley on Genesis 15:5

And he brought him forth - It seems, early in the morning, and said, look now toward heaven, and tell the stars: so shall thy seed be - So innumerable, for so the stars seem to a common eye. Abram feared he should have no child at all, but God tells him his descendents should be so many as not to be numbered. So illustrious, as the stars of heaven for splendour; for to them pertained the glory, Rom 9:4. Abram's seed according to the flesh were like the dust of the earth, Ge 13:16, but his spiritual seed are like the stars of heaven.
