Thou coveredst it with the deep That is, in the first creation, of which the psalmist is here speaking, when the earth, while yet without form, was covered all over, and, as it were, clothed with the great deep, that vast expansion of air and waters; the waters stood above the mountains Those which are now the highest mountains were all under that liquid element. At thy rebuke That is, at thy powerful command, which, as it were, rebuked, and thereby corrected and regulated that indigested congeries and confusion of things; they fled Namely, the inferior waters; at the voice of thy thunder Thy powerful voice, which resounded like thunder; they hasted away To the place that thou hadst prepared for them, where they still make their bed.
