John Gill Commentary Ezekiel 32:14

"Then will I make their waters clear, and cause their rivers to run like oil, saith the Lord Jehovah." — Ezekiel 32:14 (ASV)

Then will I make their waters deep

Either the water of Egypt literally, the waters of the Nile: no canals being cut from it, to carry the water to the several parts of the land, the land being depopulated, and no business done. Or, figuratively, other nations, compared to waters for their numbers, who before had been disturbed by the Egyptians; but now they being destroyed, these would be at ease, like troubled waters, which subside and become deep and clear, when there is none to trouble them.

And cause their rivers to run like oil, says the Lord God; very slowly, as if they were mourning the unhappy condition of the land; or smoothly, clearly, undisturbed, as before.

The Targum is, "there will I cause the people to rest, and I will lead their kings quietly, says the Lord God."
