Psalms 104:6

⁴ Who maketh his angels spirits; his ministers a flaming fire:

⁵ Who laid the foundations of the earth, that it should not be removed for ever.

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.

⁸ They go up by the mountains; they go down by the valleys unto the place which thou hast founded for them.

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