Job 38:30

“The waters are hid as [with] a stone, etc.] The surface of the waters by frost become as hard as a stone, and will bear great burdens, and admit of carriages to pass over them f1319 where ships went before; so that the waters under them are hid and quite out of sight: an emblem of the hard heart of man, which can only be thawed by the power and grace of God, by the south wind of the Spirit blowing, and the “sun of righteousness” rising on it; and the face of the deep is frozen; or bound together by the frost, as the Targum; it is taken, laid hold on, and kept together, as the word signifies, so that it cannot flow. Historians speak of seas being frozen up, as some parts of the Scythian sea,…”

“The waters are hid as with a stone - The solid ice is laid as a stone upon them, wholly concealing them from view. And the face of the deep is frozen - Margin, “taken.” The idea is, they seem to take hold of one another (יתלכדוּ yitlâkadû); they hold together, or cohere. The formation of ice is thus appealed to as a proof of the wisdom of God, and as a thing which Job could not explain. No man could produce this effect; nor could Job explain how it was done. return to 'Top of Page'”
