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, 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.”

Occurs only in Jer. 6:29, in relation to the casting of metal. Probably they consisted of leather bags similar to those common in Egypt.
