'Feign' in the Bible

And Joab sent to Tekoah, and fetched thence a wise woman, and said unto her, I pray thee, feign thyself to be a mourner, and put on now mourning apparel, and anoint not thyself with oil, but be as a woman that had a long time mourned for the dead:

And the LORD said unto Ahijah, Behold, the wife of Jeroboam cometh to ask a thing of thee for her son; for he is sick: thus and thus shalt thou say unto her: for it shall be, when she cometh in, that she shall feign herself to be another woman.

And they watched him, and sent forth spies, which should feign themselves just men, that they might take hold of his words, that so they might deliver him unto the power and authority of the governor.
