'Guard' in the Bible

Consequently, the king of Israel sent word to the place the man of God had told him about. The man of God repeatedly warned the king, so the king would be on his guard.

Then Jehu son of Jehoshaphat, son of Nimshi, conspired against Joram. Joram and all Israel had been at Ramoth-gilead on guard against Hazael king of Aram.

When Athaliah heard the noise from the guard and the crowd, she went out to the people at the Lord’s temple.
