'Feign' in the Bible

And Jonadab said to him, Lay thee down on thy bed and feign thyself sick; and when thy father comes to see thee, say to him, I pray thee, let my sister Tamar come, and give me food, and dress the food in my sight, that I may see it, and eat it from her hand.

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

And Jehovah said to Ahijah, Behold, the wife of Jeroboam cometh to ask a thing of thee about 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 to be another.
