11:12 Careth for - In a special manner watering it immediately as it were by his own hand, without man's help, and giving peculiar blessings to it, which Egypt enjoys not.

And therefore it is not at all strange that some later writers, describe the land of Canaan as a barren soil, which is, so far from affording ground to question the authority of the scriptures, that it doth much more confirm it, this, being an effect of that threatning that God would turn a fruitful land into barrenness for the wickedness of these that dwell in it, Psa 107:34.
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.

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.
