Teraphim

The word "teraphim" is explained by the Rabbis as meaning "disgraceful things" (Yer. 'Ab. Zarah ii. 41b; Tan., Wayeẓe). It is rendered "ẓalmanaya" or "ẓilmanaya" (= "images") by the Targumim of Onḳelos and pseudo-Jonathan to Gen. xxxi. 19, 34, and by the Targum of Jonathan in the other parts of the Bible, except in connection with the image of Micah (Judges xvii. 5; xviii. 14, 18, 20), where it is rendered "dema'in" (= "likenesses"). The nature of the teraphim is much discussed by ancient commentators. According to Targ. pseudo-Jonathan to Gen. xxxi. 19, the teraphim were made of the head of a man, a first-born, which, after the man had been slain, was shaved and then salted and spiced. After a golden plate on which magic words were engraved had been placed under the tongue, the mummified head was mounted on the wall, and it spoke to the people. This legend is more fully developed in Pirḳe R. El. xxxvi., where it is said that after the head had been displayed on the wall, lighted candles were placed round it; the people then prostrated themselves before it, and it talked to them.

 And Laban had gone to shear his flock; and Rahel stole the images. For they had slain a man, a firstborn, and had cut off his head; they salted it with salt and balsams, and wrote incantations on a plate of gold, and put it under his tongue, and set it up in the wall, and it spake with them; and unto such their father bowed himself.
