The separation of the priests and Levites, evidently shows in what light GOD views his servants who minister in holy things. How much is it to be wished, that all such were indeed set apart, both by the divine appointment and ordination of the LORD, and from the necessity of worldly commerce with man, for these things bring a snare. This precept and the LORD'S provision for his priests and Levites we have before: Numbers 18:9-11.
