Nehemiah 13:22

And I commanded the Levites that they should cleanse themselves, from any Levitical impurities which they might have contracted during their absence from the city, and that they should come and keep the gates, guarding the city against any further violation of the Sabbath law, to sanctify the Sabbath-day. Remember me, O my God, concerning this also, and spare me according to the greatness of Thy mercy. The example of Nehemiah may be followed in our days if the leaders of the Church and all Christians show the proper zeal for the sanctifying of the Word of God, in urging the people to hold preaching and the Gospel sacred, and gladly to hear and learn it.
