(17) Walk through the land.--Repeated change of scene is not merely one of the pleasures of the nomad life, but also a necessity; for the uplands, covered with rich herbage in the spring, are usually burnt up in summer, and in the winter are exposed to driving winds and rain-storms. In these journeyings Abram is now to have the tranquil pleasure of feeling that his seed will inherit each beautiful spot that he visits, and that he is taking possession of it, and hallowing it for them.

Verse 17. - Arise. According to a common mode of Oriental speech, pleonastically affixed to verbs of going, going forward, and of setting about anything with impulse (Gesenius, p. 727; cf. Genesis 22:3; Job 1:20). Walk through the land in the length of it and in the breadth of it. To be understood not as a literal direction, but as an intimation that he might leisurely survey his inheritance with the calm assurance that it was his. For I will give it unto thee.

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.Arise, walk through the land,.... And take a survey of it, and see what a land it is, how good and how large, and take possession of it for himself and his, though he was only to be a sojourner in it; and so the Targum of Jonathan adds, and making in it a possession, which in civil law was done by walking:

in the length of it, and in the breadth of it; the extent of it is variously settled by geographers; some giving it no more than about one hundred and seventy or eighty miles in length, from north to south, and about one hundred and forty in breadth from east to west, where broadest, as it is towards the south, and but about seventy where narrowest, as it is towards the north: but it is observed (d) from the latest and most accurate maps, that it appears to extend near two hundred miles in length, and about eighty in breadth about the middle, and ten or fifteen more or less where it widens or shrinks:

for I will give it unto thee; that is, to his seed, the whole of it, in its utmost extent, as to length and breadth; which if he pleased for his own satisfaction he might take a tour through, whereby he would be a judge what was bestowed on him and his(d) Vid. Universal History, vol. 2. p. 385.
