Genesis 13:16

As the dust, an hyperbole, to express a very numerous offspring, which is more exact, if we take in the spiritual children of Abram. (Menochius)

2. Here is the promise of a numerous issue to replenish this good land, so that it should never be lost for want of heirs (v. 16): I will make thy seed as the dust of the earth, that is, "They shall increase incredibly, and, take them altogether, they shall be such a great multitude as no man can number." They were so in Solomon's time, 1 Kings 4 20, Judah and Israel were many as the sand which is by the sea in multitude. This God here gives him the promise of. Note, The same God that provides the inheritance provides the heirs. He that has prepared the holy land prepares the holy seed; he that gives glory gives grace to make meet for glory.

Verses 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.
