Bellows

From BibleEncyclopedia.Net

bel´ōz, bel´us:

The word occurs once only in English Versions of the Bible, in Jeremiah 6:29, in relation to the casting of metal, where the prophet is predicting the coming of the destroyer (Jeremiah 6:26), “a great nation” from “the north country” (Jeremiah 6:22), down upon Israel, because “all of them deal corruptly” (Jeremiah 6:28). “The bellows blow fiercely; the leads is of the fire.” Here the imagery is drawn from the refiner's art, and the “bellows” are those used to make the refiner's fires burn fiercely. Probably they consisted of leather bags similar to those common in Egypt.

See Crafts, II, 10.
