72 Now they were ordained after this manner: Being called with a holy calling, and ordained with a holy ordinance, and taking upon them the high priesthood of the holy order, which calling, and ordinance, and high priesthood, is without beginning or end;

4 Now they, after being sanctified by the Holy Ghost, having their garments made white, being pure and spotless before God, could not look upon sin, save it were with abhorrence;
5 And there were many, exceeding great many, who were made pure, and entered into the rest of the Lord their God.
