'Feign' in the Bible

And Jonadab saith to him, 'Lie down on thy couch, and feign thyself sick, and thy father hath come in to see thee, and thou hast said unto him, 'Let, I pray thee, Tamar my sister come in and give me bread to eat; and she hath made the food before mine eyes so that I see it, and have eaten from her hand.'

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:

Sons of a stranger feign obedience to me, At the hearing of the ear they hearken to me.
