Adam Clarke Bible Commentary

So can no fountain both yield salt water and fresh - For the reading of the common text, which is οὑτως ουδεμια πηγη ἁλυκον και γλυκυ ποιησαι ὑδωρ, so no fountain can produce salt water and sweet, there are various other readings in the MSS. and versions. The word οὑτως, so, which makes this a continuation of the comparison in Jam 3:11, is wanting in ABC, one other, with the Armenian and ancient Syriac; the later Syriac has it in the margin with an asterisk. ABC, five others, with the Coptic, Vulgate, one copy of the Itala, and Cyril, have ουτε ἁλυκον γλυκυ ποιησαι ὑδωρ, neither can salt water produce sweet. In the Syriac and the Arabic of Erpen, it is, So, likewise, sweet water cannot become bitter; and bitter water cannot become sweet. The true reading appears to be, Neither can salt water produce sweet, or, Neither can the sea produce fresh water; and this is a new comparison, and not an inference from that in Jam 3:11. This reading Griesbach has admitted into the text; and of it Professor White, in his Crisews, says, Lectio indubie genuina, "a reading undoubtedly genuine." There are therefore, four distinct comparisons here: 1. A fountain cannot produce sweet water and bitter. 2. A fig tree cannot produce olive berries. 3. A vine cannot produce figs. 4. Salt water cannot be made sweet. That is, according to the ordinary operations of nature, these things are impossible. Chemical analysis is out of the question.
