In the twenty-seventh year of Asa king of Judah, Zimri reigned in Tirzah seven days. The army was encamped near Gibbethon, a Philistine town.
References for 1 Kings 16:15
When the Israelites in the camp heard that Zimri had plotted against the king and murdered him, they proclaimed Omri, the commander of the army, king over Israel that very day there in the camp.
Then Omri and all the Israelites with him withdrew from Gibbethon and laid siege to Tirzah.
When Zimri saw that the city was taken, he went into the citadel of the royal palace and set the palace on fire around him. So he died,
because of the sins he had committed, doing evil in the eyes of the LORD and following the ways of Jeroboam and committing the same sin Jeroboam had caused Israel to commit.
As for the other events of Zimri’s reign, and the rebellion he carried out, are they not written in the book of the annals of the kings of Israel?
