Psalms 104:19

The fifth decastich, in which the poet passes over from the third to the fourth day, shows that he has the order of the days of creation before his mind. The moon is mentioned first of all, because the poet wishes to make the picture of the day follow that of the night. He describes it in Psa 104:19 as the calendarial principal star. מועדים are points and divisions of time (epochs), and the principal measurer of these for civil and ecclesiastical life is the moon (cf. Sir. 43:7, ἀπὸ σελήνης σημεῖον ἑορτῆς), just as the sun, knowing when he is to set, is the infallible measurer of the day. In Psa 104:20 the description, which throughout is drawn in the presence of God in His honour, passes over into direct address: jussives (תּשׁת, ויהי) stand in the hypothetical protasis and in its apodosis (EW. 357, b). It depends upon God's willing only, and it is night, and the wakeful life of the wild beasts begins to be astir. The young lions then roar after their prey, and flagitaturi sunt a Deo cibum suum. The infinitive with Lamed is an elliptical expression of a conjugatio periphrastica (vid., on Hab 1:17), and becomes a varying expression of the future in general in the later language in approximation to the Aramaic. The roar of the lions and their going forth in quest of prey is an asking of God which He Himself has implanted in their nature. With the rising of the sun the aspect of things becomes very different. שׁמשׁ is feminine here, where the poet drops the personification (cf. Psa 19:1-14). The day which dawns with sunrise is the time for man. Both as to matter and style, Psa 104:21 call to mind Job 24:5; Job 37:8; Job 38:40.

We are here taught to praise and magnify God, I. For the constant revolutions and succession of day and night, and the dominion of sun and moon over them. The heathen were so affected with the light and influence of the sun and moon, and their serviceableness to the earth, that they worshipped them as deities; and therefore the scripture takes all occasions to show that the gods they worshipped are the creatures and servants of the true God (Psa 104:19): He appointed the moon for seasons, for the measuring of the months, the directing of the seasons for the business of the husbandman, and the governing of the tides. The full and change, the increase and decrease, of the moon, exactly observe the appointment of the Creator; so does the sun, for he keeps as punctually to the time and place of his going down as if he were an intellectual being and knew what he did. God herein consults the comfort of man. 1. The shadows of the evening befriend the repose of the night (Psa 104:20): Thou makes darkness and it is night, which, though black, contributes to the beauty of nature, and is as a foil to the light of the day; and under the protection of the night all the beasts of the forest creep forth to feed, which they are afraid to do in the day, God having put the fear and dread of man upon every beast of the earth (Gen 9:2), which contributes as much to man's safety as to his honour. See how nearly allied those are to the disposition of the wild beasts who wait for the twilight (Job 24:15) and have fellowship with the unfruitful works of darkness; and compare to this the danger of ignorance and melancholy, which are both as darkness to the soul; when, in either of those ways, it is night, then all the beasts of the forest creep forth. Satan's temptations then assault us and hav…

104:19-23 The psalmist rejoices in the order of night and day, marking day four of creation (Gen 1:14-19). This cycle gives all creatures an opportunity to live. 104:19 the moon to mark the seasons: Ancient Israel based its calendar on the cycles of the moon. • the sun knows when to set: This is a poetic description from the perspective of normal observation. The sun goes down at a regular time every evening.
