So I separated from them all strangers: and I appointed the courses of the priests and the Levites, every man in his ministry:
And that we would not give our daughters to the people of the land, not take their daughters for our sons.
And the priests and the Levites purified: and they purified the people, and the gates, and the wall.
But the Lord is our God, whom we forsake not, and the priests who minister to the Lord are the sons of Aaron, and the Levites are in their order.
