'Seventh Year' in the Bible

Zimri came in and struck him dead. (This happened in the twenty-seventh year of Asa's reign over Judah.) Zimri replaced Elah as king.

In the twenty-seventh year of Asa's reign over Judah, Zimri became king over Israel; he ruled for seven days in Tirzah. Zimri's revolt took place while the army was deployed in Gibbethon, which was in Philistine territory.
