Melachim Alef 16:24-26

Orthodox Jewish Bible

²⁴ And he bought the Har Shomron from Shemer for two talents of kesef, and built on the hill, and called the shem of the Ir which he built, after the shem of Shemer, adonei hahar (owner of the hill), Shomron.

²⁵ But Omri wrought rah in the eyes of Hashem, and did sin more than all that were before him.

²⁶ For he walked in all the derech Yarov‘am Ben Nevat, and in his chattat wherewith he made Yisroel to sin, to provoke Hashem Elohei Yisroel to anger with their havalim (vanities, nothingnesses, i.e., idols)
