'Keeper' in the Bible

And David rose up early in the morning, and left the sheep with a keeper, and took his charge and went, as Jesse had commanded him. And he came to the wagon-defence; and the host which was going forth to the battle-array shouted for the fight.

And David left the things he was carrying in the hand of the keeper of the baggage, and ran into the ranks, and came and saluted his brethren.

And David said to Achish, Thereby thou shalt know what thy servant can do. And Achish said to David, Therefore will I make thee keeper of my person for ever.
