Verse 16. - And I will make thy seed as the dust of the earth. "As the land shall be great for thy people, thy posterity, so thy people shall be great or innumerable for the land" (Lunge). Afterwards the seed of Abram is likened to the stars of heaven for multitude (Genesis 15:5). So that if a man can number the dust of the earth, then shall thy seed also be numbered.

13:14-18 Those are best prepared for the visits of Divine grace, whose spirits are calm, and not ruffled with passion. God will abundantly make up in spiritual peace, what we lose for preserving neighbourly peace. When our relations are separated from us, yet God is not. Observe also the promises with which God now comforted and enriched Abram. Of two things he assures him; a good land, and a numerous issue to enjoy it. The prospects seen by faith are more rich and beautiful than those we see around us. God bade him walk through the land, not to think of fixing in it, but expect to be always unsettled, and walking through it to a better Canaan. He built an altar, in token of his thankfulness to God. When God meets us with gracious promises, he expects that we should attend him with humble praises. In outward difficulties, it is very profitable for the true believer to mediate on the glorious inheritance which the Lord has for him at the last.And I will make thy seed as the dust of the earth,.... An hyperbolical expression denoting the great multitude of Abram's posterity, as they were in the days of Solomon, and as they will be in the latter day; and especially as this may respect all the spiritual seed of Abram, Jews and Gentiles, and as they will be in the spiritual reign of Christ, see Hosea 1:10,

so that if a man can number the dust of the earth, then shall thy seed be numbered; but as it is impossible to do the one, so the other is not practicable, see Numbers 23:10.
