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.
