'Sons of Levi' in the Bible

Then the priests, the sons of Levi, will come forward, for Yahweh your God has chosen them to serve Him and pronounce blessings in His name, and they are to give a ruling in every dispute and case of assault.

Moses wrote down this law and gave it to the priests, the sons of Levi, who carried the ark of the Lord’s covenant, and to all the elders of Israel.
