As their brothers the descendants of Aaron did, they also cast lots in the presence of King David and of Zadok, Ahimelech, and the heads of the families of the priests and Levites—the family heads and their younger brothers alike.
Jewish Publication Society of America Version (JPS1917) - 1 Chronicles 24:31 >These likewise cast lots even as their brethren the sons of Aaron in the presence of David the king, and Zadok, and Ahimelech, and the heads of the fathers' houses of the priests and of the Levites; the fathers' houses of the chief even as those of his younger brother.
