Psalms 104:10

“He sendeth the springs into the valleys, etc.] The Targum is, “who sendeth fountains into the rivers.” Either from the waters of the sea, which being drained through the sand, become sweet and drinkable; or from the hills and mountains. This is an instance of divine goodness, that having removed the waters from the earth, and shut them up in the sea, and which, through the saltness of them, not being proper drink for men and beasts, he has been pleased to form and open springs, fountains, wells, and rivers of fresh water in the valleys, for the supply of both. Though this is not to be compared with the wells of salvation, and springs and fountains of grace, which he has opened for his chosen…”

“He sendeth the springs into the valleys - Though the waters are gathered together into seas, yet God has taken care that the earth shall not be dry, parched, and barren. He has made provision for watering it, and by a most wise, wonderful, and benevolent arrangement, he has formed springs among the valleys and the hills. It is now animated nature which comes before the eye of the psalmist; and all this he traces to the fact that the earth is “watered,” and that it is not a waste of rocks and sands. The allusion in this part of the psalm (see the Introduction) is to the earth as covered with vegetation - or, to the third day of the week of creation Genesis 1:9-13, which, in Genesis, is…”

“He sendeth: Heb.

Deu 8:7; Isa 35:7, Isa 41:18 run: Heb. walk Psalms 104:11”

“The third decastich, passing on to the third day of creation, sings the benefit which the shore-surrounded waters are to the animal creation and the growth of the plants out of the earth, which is irrigated from below and moistened from above. God, the blessed One, being the principal subject of the Psalm, the poet (in Psa 104:10 and further on) is able to go on in attributive and predicative participles: Who sendeth springs בּנּחלים, into the wads (not: בּנחלים, as brooks). נחל, as Psa 104:10 shows, is here a synonym of בּקעה, and there is no need for saying that, flowing on in the plains, they grow into rivers. The lxx has ἐν φάραγξιν. חיתו שׂדי is doubly poetic for חיּת השּׂדה. God has…”
