The scribe Shemaiah son of Nethanel, a Levite, wrote down their names before the king, the officials, Zadok the priest, Ahimelech son of Abiathar, and the leaders of the priestly and Levite families. One family was drawn by lot from Eleazar, and then the next from Ithamar. ¹ 

Just like their relatives, the descendants of Aaron, they also cast lots before King David, Zadok, Ahimelech, the leaders of families, the priests, and the Levites. The families of the oldest son cast lots along with the those of the youngest. ¹ 

Hezekiah appointed the divisions of the priests and Levites to do their assigned tasks ¹  – to offer burnt sacrifices and present offerings and to serve, give thanks, and offer praise in the gates of the Lord’s sanctuary. ² 

His officials also willingly contributed to the people, priests, and Levites. Hilkiah, Zechariah, and Jehiel, the leaders of God’s temple, supplied 2,600 Passover sacrifices and 300 cattle.

On that day men were appointed over the storerooms for the contributions, first fruits, and tithes, to gather into them from ¹  the fields of the cities the portions prescribed by the law for the priests and the Levites, for the people of Judah ²  took delight in the priests and Levites who were ministering. ³
