'Conspired' in the Bible

So Ahijah's son Baasha from the household of Issachar conspired against him and killed Nadab at Gibbethon in Philistia while Nadab and all of Israel were attacking Gibbethon.

But his servant Zimri, who commanded half of his chariot forces, conspired against Elah while he was drinking himself drunk in the home of Arza, who managed the household at Tirzah.

The army at the encampment heard this report: "Zimri has conspired against the king and killed him." So the entire army of Israel made Omri, their commander, king over Israel.
