'Conspired' in the Bible

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

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

The people who were camped heard it said, “Zimri has conspired and has also struck down the king.” Therefore all Israel made Omri, the commander of the army, king over Israel that day in the camp.
