Psalms 104:8

⁶ You covered it with the deep like a garment; the waters stood above the mountains.

⁷ At Your rebuke the waters fled; at the sound of Your thunder they hurried away—

the mountains rose and the valleys sank to the place You assigned for them—

⁹ You set a boundary they cannot cross, that they may never again cover the earth.

¹⁰ He sends forth springs in the valleys; they flow between the mountains.

Do read the surrounding verses too, because the context often says more than a single verse.
