TSK · Ezra 3:10

“For Aaron’s sons you are to make tunics, sashes, and headbands for glory and for beauty.

Then the king said to Doeg,“You turn and strike down the priests!” So Doeg the Edomite turned and struck down the priests. He killed on that day eighty-five men who wore the linen ephod.

Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer the priests were to blow the trumpets before the ark of God; Obed-Edom and Jehiel were also guardians of the ark.

He appointed some of the Levites to serve before the ark of the LORD, to offer prayers, songs of thanks, and hymns to the LORD God of Israel.

Heman and Jeduthun were in charge of the music, including the trumpets, cymbals, and the other musical instruments used in praising God. The sons of Jeduthun guarded the entrance.

David Organizes the Musicians David and the army officers selected some of the sons of Asaph, Heman, and Jeduthun to prophesy as they played stringed instruments and cymbals. The following men were assigned this responsibility:

the eighteenth to Hanani and his sons and relatives– twelve in all,

Hezekiah stationed the Levites in the LORD’s temple with cymbals and stringed instruments, just as David, Gad the king’s prophet, and Nathan the prophet had ordered.(The LORD had actually given these orders through his prophets.)

The musicians, the descendants of Asaph, manned their posts, as prescribed by David, Asaph, Heman, and Jeduthun the king’s prophet. The guards at the various gates did not need to leave their posts, for their fellow Levites made preparations for them.

And the leaders of the Levites were Hashabiah, Sherebiah, Jeshua son of Kadmiel, and their colleagues, who stood opposite them to offer praise and thanks, one contingent corresponding to the other, as specified by David the man of God.
