Charles H. Spurgeon on Psalms 104:22

The sun ariseth...they lay them down in their dens. As wild beasts since the fall of man may seem to be born to do us hurt, and to rend and tear in pieces all whom they meet with, this savage cruelty must be kept under check by the providence of God. And in order to keep them shut up within their dens, the only means which he employs is to inspire them with terror, simply by the light of the sun. This instance of divine goodness, the prophet commends the more on account of its necessity; for were it otherwise, men would have no liberty to go forth to engage in the labours and business of life. John Calvin.
