Bellows. The word occurs only in Jeremiah 6:29, where it denotes an instrument to heat a smelting furnace. Wilkinson in "Ancient Egypt," iii. 338, says, "They consisted of a leather bellows, secured and fitted into a frame, from which a long pipe extended for carrying the wind to the fire. They were worked by the feet, the operator standing upon them, with one under each foot, and pressing them alternately, while he pulled up each exhausted skin with a string he held in his hand."
