'Guard' in the Bible

Now Adonijah, son of David and Haggith, was promoting himself, boasting, "I will be king!" He managed to acquire chariots and horsemen, as well as fifty men to serve as his royal guard.

King Rehoboam made bronze shields to replace them and assigned them to the officers of the royal guard who protected the entrance to the royal palace.

Whenever the king visited the Lord's temple, the royal guard carried them and then brought them back to the guardroom.

When the king passed by, he called out to the king, "Your servant went out into the heat of the battle, and then a man turned aside and brought me a prisoner. He told me, 'Guard this prisoner. If he ends up missing for any reason, you will pay with your life or with a talent of silver.'
