Deuteronomy 11:12 - Matthew Poole's English Annotations on the Holy Bible

Land which the Lord careth for, to wit, 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. The eyes of the Lord are always upon us, 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, as it here follows. And therefore it is not at all strange that some later writers decry the land of Canaan as in great part a barren soil, which is so far from affording any ground to question the Divine authority of the Holy Scriptures, in which its fruitfulness is declared, that it doth much more confirm it, this being but an effect of that threatening that God would turn a fruitful land into barrenness for the wickedness of those that dwell in it, Psalms 107:34, and elsewhere; and the wickedness of the Israelites in succeeding ages being notorious, it is but just and fit that the barrenness of their land should be as evident and infamous.
