But the land whither ye go to possess it is a land of hills and valleys,.... And so could not be watered by the overflow of a river, and by canals cut out of it, and in the manner Egypt was; which was for the most part a plain and flat country, but not so Canaan, in which were many hills and mountains, as those about Jerusalem, Carmel, Tabor, Lebanon, and others; and plains and valleys, as the valley of Jezreel, &c. and which made it more delightful and pleasant for prospects; see Deuteronomy 8:7 and drinketh water of the rain of heaven; by which it was watered, refreshed, and made fruitful; not by means of men, but by the Lord himself, and so with much more ease to men, and without the toil and labour they were obliged to in Egypt, as well as it was both more healthful and pleasant; for the damps that arose from the overflow of the Nile were sometimes prejudicial to health; and during the season of its overflow, which was in the summer, they were obliged to keep in their houses, and could not walk abroad for weeks together; to which inconveniences the land of Canaan was not subject; but then, as its fertility depended on rain from heaven, the Israelites would be under the greater obligation to observe the commands of God, who could give and withhold it at his pleasure, and as they conducted themselves; which seems to be the general drift of this passage.

But the land, whither ye go to possess it, is a land of hills and valleys, and drinketh water of the rain of heaven:

11:11 Of hills and valleys - And therefore much more healthful than Egypt was, which as it was enriched, so it was annoyed with the Nile, which overflowed the land in summer time, and thereby made the country both unpleasant and unhealthful. And health being the greatest of all outward blessings, Canaan must therefore needs be a more desirable habitation than Egypt. The rain of heaven - Which is more easy, being given thee without thy charge or pains; more sweet and pleasant, not hindering thy going abroad upon thy occasions, as the overflow of the Nile did, whereby the Egyptians were confined in a great measure to their houses; more safe and healthful, being free from that mud which attends upon the waters of the Nile; and more certain too, the former and the latter rain being promised to be given to them in their several seasons, upon condition of their obedience, which condition, tho' it may seem a clog and inconvenience, yet indeed was a great benefit, that by their own necessities and interest they might be obliged to that obedience, upon which their happiness depended both for this life and the next.

11:8-17 Moses sets before them, for the future, life and death, the blessing and the curse, according as they did or did not keep God's commandment. Sin tends to shorten the days of all men, and to shorten the days of a people's prosperity. God will bless them with an abundance of all good things, if they would love him and serve him. Godliness has the promise of the life that now is; but the favour of God shall put gladness into the heart, more than the increase of corn, and wine, and oil. Revolt from God to idols would certainly be their ruin. Take heed that your hearts be not deceived. All who forsake God to set their affection upon any creature, will find themselves wretchedly deceived, to their own destruction; and this will make it worse, that it was for want of taking heed.
