(Hebrew, "mappuach.") An implement well known to the Hebrews from olden times. (Jer. 6:29) As made in Egypt, they consisted of leather secured 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, one under each foot, and pressing them alternately down and pulling the empty skin up by means of a string. They may also have had the smaller bellows, made of wood and skin, of the kind which still are in use in many countries.
