Psalms 104:19

19. The psalmist passes to the fourth day’s work. Genesis 1:14.

The moon for seasons The day was determined by the apparent revolutions of the sun, the week, by the return of the sabbath, (Genesis 2:2; Exodus 20:11,) but the year, which was a division of time first suggested by summer and winter, and the regular returning fruits of the earth, was early reckoned by lunar months. The word “signs,” (Genesis 1:14,) is not to be understood of portents, but of division marks of time.

Sun knoweth his going down The time and place, as if he were endowed with knowledge. See Job 38:12. The allusion is to the exactness of the apparent motion of the sun, or the diurnal revolution of the earth. But this is only as a drop to the ocean compared with all the motions of the heavenly bodies and systems of worlds. So perfect are the works of God!
