Melachim Alef 21:25-27

Orthodox Jewish Bible

²⁵ But there was none like unto Ach’av, which did sell himself to work rah before the eyes of Hashem, whom Izevel his isha urged on.

²⁶ And he acted monstrously in going after gillulim (idols), according to all things as did HaEmori, whom Hashem drove out before the Bnei Yisroel.

²⁷ And it came to pass, when Ach’av heard those words, that he tore his begadim, put sackcloth upon his basar, did a tzom, lay in sackcloth, and walked about subdued.
