“Then the Levites arose. Mahath son of Amasai and Joel son of Azariah, of the sons of the Kohathites arose. Of the sons of Merari, Kish son of Abdi and Azariah son of Jehallelel arose. Of the Gershonites, Joah son of Zimmah and Eden son of Joah arose. The sons of Elizaphan, Shimri and Jeuel also arose. Of the sons of Asaph, Zechariah and Mattaniah arose. Of the sons of Heman, Jehuel and Shimei arose. Of the sons of Jeduthun, Shemaiah and Uzziel arose. They gathered their brothers. They sanctified themselves. They went in as the king had commanded, by the words of Yahweh, to cleanse the house of Yahweh.”
The Levites responded positively. 2 people from each of the Levitical tribes arose from the Kohathites, the Merarites, and the Gershonites. The same was true for the 3 groups of singers or cantors, the sons of Asaph, Heman, and Jeduthun, all had 2 people stand up. On top of that, the sons of Elizaphan, Shimri and Jeuel also rose up. They gathered their brother Levites and sanctified themselves. Then they went in to cleanse the house of Yahweh. I wonder why they had not done more to sustain the house of Yahweh even in the face of indifference.
