2SA 14:2

2 and he sent to Tekoah, and took from thence a wise woman, and he said to her, Feign thee to mourn, and be thou clothed with a cloak of dole, and be thou not anointed with oil, that thou be as a woman by mourning now in full much time a dead man (or so that thou be like a woman now after a great deal of time mourning for her husband).
