Psalms 104:8

⁶ Thou coveredst it with the deep as with a garment: the waters stood above the mountains.

⁷ At thy rebuke they fled; at the voice of thy thunder they hasted away.

They go up by the mountains; they go down by the valleys unto the place which thou hast founded for them.

⁹ Thou hast set a bound that they may not pass over; that they turn not again to cover the earth.

¹⁰ He sendeth the springs into the valleys, which run among the hills.

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