'Sons of Levi' in the Bible

for unto the chambers do they bring in -- the sons of Israel and the sons of Levi -- the heave-offering of the corn, the new wine, and the oil, and there are vessels of the sanctuary, and the priests, those ministering, and the gatekeepers, and the singers, and we do not forsake the house of our God.

The sons of Levi, the chief of the fathers, were written in the book of the chronicles, even until the days of Johanan the son of Eliashib.
