'Guard' in the Bible

“He guards the feet of His godly (faithful) ones,But the wicked ones are silenced and perish in darkness;For a man shall not prevail by might.

And the king said to the guards who stood around him, “Turn around and kill the priests of the Lord, because their loyalty also is with David, and because they knew that he was fleeing and did not inform me.” But the servants of the king were not willing to put out their hands to attack the Lord’s priests.
