Psalms 33:7 - Joseph Benson’s Commentary on the Old and New Testaments

He gathereth the waters Or, gathered, for he seems to speak of the first creation when this was done, Genesis 1. Or, he alludes to the passage of the Israelites through the Red sea, when the waters were as a wall unto them on the right hand and on the left. As a heap By which expression he leads our thoughts to that great work of God by which the sea, which is specifically lighter than the earth, and by the common laws of gravitation, should rise above and overflow it, is yet kept within proper bounds; which is often mentioned in Scripture as an immediate effect of God's overruling power and providence. To this may be added that the adjusting the proportion of the tides, so that they rise no higher to the prejudice of the lower grounds, is another remarkable instance of God's especial providence. He layeth up the depth in store-houses That is, either in the clouds, or in the bowels of the earth, whence he can draw them forth when he sees fit. Dr. Waterland renders this clause, He layeth them up in the store-houses of the deep.
