-Teraphim:.Teraphim were givers of prosperity, idols in human shape, large or small, analogous to the images of ancestors which were revered by the Romans. 

In order to deceive the guards sent by Saul of the Old Testament to seize David, Michal his wife prepared one of the household teraphim, putting on it the goat's hair cap worn by sleepers and invalids and laid it in a bed, covering it with a mantle. She pointed it out to the soldiers and alleged that David was confined to his bed by a sudden illness:.1Samuel 19:13-16. Thus she gained time for David's escape. It seems strange to read of teraphim, images of ancestors, preserved for superstitious purposes, being in the house of David. Probably they had been stealthily brought by Michal from her father's house.

In another case, that of ancient Jacob being told by God to flee from his uncle Laban, whom he worked 14 years for, in order to have his two daughters as partners, one of the girls, Rachel took two images called teraphim in the original. She took the two images along with her when she and her sister Leah left with Jacob. The story:.Genesis 30:43 to 31:1-35.
