John Trapp on Psalms 74:16

Verſ. 16. The day is thine, the night alſo is thine] He had argued with God, and ſtrengthened his own faith from Gods extraordinary works; and now he doth the like from his ordinary works in nature, with the alternal courſe thereof, wherein appeareth a kind of image of the ſeaſonable driving away of calamities, and turning all things into a deſired ſtate, Pſal. 30.5. Lam. 3.23.

Thou haſt prepared the light and the Sun] i. e. That firſt light ſcattered abroad the heavens, but afterwards gathered into the Sun, as into a veſſel. By light ſome underſtand here the Moon, that other great luminary; it being the manner of the Hebrews, nomen generis reſtringere ad ſpeciens deteriorem.
