Charles H. Spurgeon on Psalms 89:32

Then will I visit their transgression with the rod, etc. He does not simply say, I will smite them; but, I will visit with the rod. It is one thing merely to smite, it is another thing to smite by visiting. For visitation implies oversight and paternal care. The metaphor is taken from those who undertake to watch over the sick, or train up children, or tend sheep. He does not say, I will visit them with the rod; but, I will visit their transgression with the rod. We ought to think perpetually, what it is the rod of God visits in us, that we may confess our transgressions, and amend our lives. —Musculus.
