The idea is nearly the same, though not the words. The verse in Isaiah is literally this— For fill the earth shall the knowledge of Jehovah, Like the waters spreading over the sea. The verb rendered “cover” here and in Isaiah is, [כסה], which means first to spread, and in the second place to cover, as the effect of spreading. It is followed here by [על], over, and by [ל], over, in Isaiah; and so spreading must be the idea included in the verb. The comparison in Isaiah is between knowledge and waters, and the earth and the sea. Hence the common version does not properly present the comparison. The verb [מלא], is used in a passive and active sense. See Genesis 6:13, and Genesis 1:22; 24:16. This verse may be rendered in Welsh word for word, without changing the order in one instance:— Canys henwa y ddaear wybodaeth o Jehova, Vel y dyvroedd dros y more yn ymdaenu. “The knowledge of Jeohovah,” [דעה את-יהוה], is not an instance of a genitive case by juxtaposition, which is common both in Hebrew and in Welsh; for [את] here must be a preposition, “from,” for it is sometimes used for [מאת]. It is a knowledge that was to come from Jehovah, and not a knowledge of Jehovah.—Ed.
