Psalms 65:9,10 - Joseph Benson’s Commentary on the Old and New Testaments

Thou visitest In mercy, or with thy favour, the earth, and waterest it The whole earth, which is full of thy bounty. So understood, he continues to speak of the general providence of God over all people. Or, he may mean, Thou visitest the land Namely, the land of Israel; and so he proceeds, from God's general providence over all places and nations, to his particular and special providence over his people in the land of Canaan, whereof he gives one eminent and considerable instance, namely, his giving them rain and fruitful seasons, and that after a time of drought and scarcity, to which, it is not improbably supposed, this Psalm refers. And this may be the particular occasion, for which the psalmist said, that praise waited for God in Zion. Thou enrichest it with the river of God With rain, which he calls a river for his plenty, and the river of God, because it is of his immediate providing; which is full of water The clouds, like a vast river, are never exhausted, or, if they empty themselves upon the earth, they are soon and easily replenished again. Thou preparest them corn By these means thou causest the earth to bring forth and ripen corn for its inhabitants; when thou hast so provided for it Hebrew, כן תכינה, cheen techineah, hast so ordered, disposed, or prepared it; namely, the earth by thus watering it, which would otherwise be hard and barren. Thou settlest the furrows thereof Which are turned up by the plough or spade. Or, thou bringest them down, as נחת, nachath, rather signifies: for the rain dissolves the high and hard clods of the earth. Thou blessest the springing thereof When all is done, the fruitfulness of the earth must not be ascribed to the rain or sun, or any second causes, but to thy blessing alone.
