'Guard' in the Bible

Guard my soul and deliver me;Do not let me be ashamed, for I take refuge in You.

For the choir director, for Jeduthun. A Psalm of David.I said, “I will guard my waysThat I may not sin with my tongue;I will guard my mouth as with a muzzleWhile the wicked are in my presence.”

For He will give His angels charge concerning you,To guard you in all your ways.

The Lord will guard your going out and your coming inFrom this time forth and forever.

Set a guard, O Lord, over my mouth;Keep watch over the door of my lips.
