He gathereth; or, gathered; for he speaks of the first creation, when this was done, Ge 1. As an heap; by which expression he brings to our minds this great work of God, that the sea, which is lighter and higher than earth, is yet confined within its bounds, that it might not overflow the earth. In storehouses; either in the clouds, or in the bowels of the earth; whence he can draw them forth when he sees fit.
