Leviticus 10:11

That ye may teach. The priests were teachers. It was their work to instruct the people in the statutes and ways of God. But how could they do this if they themselves were unable to discern the difference between right and wrong? With a befuddled brain it is impossible to teach or lead others in the way they should go.

Spoken ...by the hand of Moses. To this day there are some who disparage Moses. Let such know that it was God who spoke through him, for in these words God endorsed his life and work. Christ said, “Had ye believed Moses, ye would have believed me. . . . But if ye believe not his writings, how shall ye believe my words?” (John 5:46, 47). True, some provisions were for Israel alone, and applied to local conditions. But such can easily be discerned. The eternal principles that God communicated “by the hand of Moses” are of as much force and value as ever. Let every Christian ponder the words of Christ: “If ye believe not his writings, how shall ye believe my words?” This pronouncement cannot lightly be put aside, for it was spoken by Christ.
