Deuteronomy 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. To the end of the year — To give it the rain, and other blessings proper to the several seasons. But all these mercies, and the fruitfulness of the land consequent upon them, were suspended upon their disobedience. 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, Psalms 107:34.
