Jeremias 50:38

A drought is upon her waters. — Better, A sword. The Hebrew word for “drought” has the same consonants as that for “sword,” with different vowel-points. In the original text the form of the two words must have been identical, as the vowel-points were of later introduction. The editors of the present text were probably guided by the thought that the context in this case determined the meaning of the word as meaning “drought,” and not a “sword.” So in Deuteronômio 28:22 the text of the Authorised version gives “sword,” and the margin “drought.” There is, however, a certain loss of rhetorical emphasis in the change of the word with which the three previous verses had begun. The “waters” include the canals of Babylon as well as the Euphrates.

They are mad upon their idols. — The word for “idols” means literally “terrors,” or “objects of terror,” as in Salmos 88:16; Jó 20:25, and this is the only place in which it is used of the objects of worship. In Gênesis 14:5; Deuteronômio 2:10 it appears as the name of the Emim, probably as meaning “the terrible, or gigantic ones.” Here it seems used for the colossal figures — winged bulls, human-headed lions, and the like — which were the objects of Babylonian worship. (See note on Jeremias 49:16.)
