'Priests and Levites' in the Bible

And they did not depart from the commandment of the king to the priests and Levites in any manner or concerning the storehouses.

This is the thing which you shall do: one third of you, of the priests and Levites who come in on the sabbath, shall be gatekeepers,

He gathered the priests and Levites and said to them, “Go out to the cities of Judah and collect money from all Israel to repair the house of your God annually, and you shall do the matter quickly.” But the Levites did not act quickly.

Then they slaughtered the Passover lambs on the fourteenth of the second month. And the priests and Levites were ashamed of themselves, and consecrated themselves and brought burnt offerings to the house of the Lord.
