TSK · 1 Chronicles 23:30

These are they whom David set over the service of song in the house of Yahweh, after that the ark had rest.

So he left there, before the ark of the covenant of Yahweh, Asaph and his brothers, to minister before the ark continually, as every day's work required;

Moreover, David and the captains of the army set apart for the service certain of the sons of Asaph, and of Heman, and of Jeduthun, who should prophesy with harps, with stringed instruments, and with cymbals: and the number of those who did the work according to their service was:

Hezekiah appointed the divisions of the priests and the Levites after their divisions, every man according to his service, both the priests and the Levites, for burnt offerings and for peace offerings, to minister, and to give thanks, and to praise in the gates of the camp of Yahweh.

It is a good thing to give thanks to Yahweh, to sing praises to your name, Most High;

Look! Praise Yahweh, all you servants of Yahweh, who stand by night in Yahweh's house!

House of Israel, praise Yahweh! House of Aaron, praise Yahweh!

Now when he had taken the book, the four living creatures and the twenty-four elders fell down before the Lamb, each one having a harp, and golden bowls full of incense, which are the prayers of the saints.
