This chapter informs us of a gracious appearance of God to Abram, and of a kind promise made unto him, Ge 15:1; of Abram's request for an heir, Ge 15:2,3; of an answer to it, that he should have one, and even a numberless seed, Ge 15:4,5; which he gave credit to, Ge 15:6; upon which he has a fresh promise of the land of Canaan, Ge 15:7; of his inheriting of which he desires a sign, and this was given him, Ge 15:8-12; and at the same time it was predicted to him how long his posterity should be afflicted in a land not theirs, and afterwards come out with great substance, Ge 15:13-16; and the grant of the land of Canaan to his seed is renewed, Ge 15:17-21.
