Zimri, servant of Elah, killed his master in the second year of his reign, the 27th year of Asa, the year 3010, and he reigned seven days in Tirtzah and killed all the house of Ba'asha [(Tzemach David)].

Omri [in my opinion was from the tribe of Efrayim (Seder HaKabbalah)], reigned for 12 years. He was the commander of the army of Israel and they made him king. And Omri went up against Zimri, and Zimri burned the king's house upon himself [(Melachim 1 16)]. And the people were divided—half followed Tivni son of Ginat to make him king and half followed Omri—for a period of five cut-short years [(Tzemach David) (and in the Yalkut, Melachim 1 16, in the name of Seder Olam, the division was for four years)].
