Unit 1 (v. 8a): The one to seek is identified by what he made
The text points to “him” by describing his works: he “makes the Pleiades and Orion.” Naming these star groups places the focus on a maker who orders the heavens and is not limited to Israel’s borders or shrines.
Unit 2 (v. 8b): He controls reversals of darkness and light
He “turns the shadow of death into the morning” and also “makes the day dark with night.” The point is not only regular sunrise and sunset, but that he can change conditions from extreme darkness to light, and from light to darkness, whenever he chooses.
Unit 3 (v. 8c): He commands the waters that fall on the land
He “calls for the waters of the sea” and “pours them out on the surface of the earth.” The wording portrays the sea as a reservoir he can summon from, resulting in poured-out waters—suggesting storms, flooding, or overwhelming downpour at his command.
Unit 4 (v. 8d–9): His name and his power over human strength
The line “Yahweh is his name” anchors these acts to Israel’s covenant name for God. Then the same “who” continues: he brings sudden ruin on “the strong,” so that destruction reaches even “the fortress.” Strength and defenses that look secure can be quickly undone.
