'Body guards' in the Bible

Benaiah the son of Jehoiada was [head] over both the Cherethites and Pelethites [the king’s bodyguards]; and David’s sons were chief [confidential] advisers (officials) [to the king].

All of David’s servants passed on beside him, and all the Cherethites, Pelethites and the Gittites, six hundred men who had come with him from Gath, passed on before the king.

So Joab’s men went after him, along with [David’s bodyguards] the Cherethites and Pelethites and all the warriors; they went out from Jerusalem to pursue Sheba the son of Bichri.

Now Joab was [commander] over the entire army of Israel; Benaiah the son of Jehoiada was [commander] over the Cherethites and Pelethites [the king’s bodyguards];

So Zadok the priest, Nathan the prophet, Benaiah the son of Jehoiada, the Cherethites, and the Pelethites [the king’s bodyguards] went down [from Jerusalem] and had Solomon ride on King David’s mule, and brought him to [the spring at] Gihon.

Ahab said, “By whom?” And he said, “Thus says the Lord: ‘By the young men [the attendants or bodyguards] of the governors of the districts.’” Then Ahab said, “Who shall begin the battle?” And he answered, “You.”

and Benaiah the son of Jehoiada was in charge of the Cherethites and the Pelethites [David’s bodyguards], and the sons of David were chiefs at the king’s side.
