'Encamping' in the Bible

In the twenty and seventh year of Asa king of Judah, reigned hath Zimri seven days in Tirzah; and the people are encamping against Gibbethon, which is to the Philistines;

and the people who are encamping hear, saying, 'Zimri hath conspired, and also hath smitten the king;' and all Israel cause Omri head of the host to reign over Israel on that day in the camp.
