assigned to 'watch over'

Thomas S. Monson: Every one of you [teachers and priests] should be given the assignment to home teach with a companion who holds the Melchizedek Priesthood. What an opportunity to prepare for a mission. What a privilege to learn the discipline of duty. A young man will automatically turn from concern for self when he is assigned to 'watch over' others (D&C 20:53).
