1 Chronicles 24:5; 1 Chronicles 24:31

5 Thus they were divided by lot, the one as the other; for they were officers of the sanctuary and officers of God, both from the descendants of Eleazar and the descendants of Ithamar.

31 These also cast lots just as their relatives the sons of Aaron in the presence of David the king, Zadok, Ahimelech, and the heads of the fathers' households of the priests and of the Levites -the head of fathers' households as well as those of his younger brother.
