'Conspired' in the Bible

Baasha the son of Ahijah, of the house of Issachar, conspired against him; and Baasha struck him at Gibbethon, which belonged to the Philistines; for Nadab and all Israel were laying siege to Gibbethon.

His servant Zimri, captain of half his chariots, conspired against him. Now he was in Tirzah, drinking himself drunk in the house of Arza, who was over the household in Tirzah:

The people who were encamped heard say, Zimri has conspired, and has also struck the king: therefore all Israel made Omri, the captain of the army, king over Israel that day in the camp.
