Only be strong and very courageous, to observe to do according to all the law, which Moses my servant commanded you: don't turn from it to the right hand or to the left, that you may have good success wherever you go.
Jesus said, "If any man would be chief among you, let him be the servant of all"( Mark 10:44 ). So a true minister is a man who is there not to be ministered to, but who is there to serve the needs of the people. So when it reads that he was Moses' servant, or his minister, it means that he was Moses' personal servant. He accompanied Moses, he helped Moses do the things, and Moses was, he was just his valet sort of, just his servant.
