And the singers, the descendants of Asaph, [were] at their stations according to the decree of David and Asaph and Heman and Jeduthun, the seer of the king. And the gatekeepers [were] at {each gate}. They did not need to depart from their service, for their brothers the Levites had made preparations for them.

and all the Levitical singers--Asaph, Heman, Jeduthun, their sons, their brothers, dressed [in] fine linen, with cymbals, harps, and stringed instruments--[they] were standing to the east of the altar. And with them outside [were] one hundred and twenty priests [who were] trumpet blowers.

And from the descendants of Elizaphan: Shimri and Jeiel; and from the descendants of Asaph: Zechariah and Mattaniah;

Then King Hezekiah and the princes commanded the Levites to praise Yahweh with the words of David and Asaph the seer. So they offered praise with joy, and they bowed down and worshiped.

Then the Spirit of Yahweh came upon Jahaziel, the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, the Levite from the descendants of Asaph, in the midst of the assembly.
