Deuteronomy 11:12

Which the Lord 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 enjoyed 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 much more confirms it, this being an effect of that threatening, that God would turn a fruitful land into barrenness for the wickedness of those that dwelt in it, Psalms 107:34.
