He appointed some of the Levites as ministers before the ark of the Lord, to celebrate and to thank and praise the Lord God of Israel:

Sing to Him, sing praises to Him; Speak of all His wonders.

For great is the Lord, and greatly to be praised; He also is to be feared above all gods.

Then say, “Save us, God of our salvation, And gather us and save us from the nations, To give thanks to Your holy name, And glory in Your praise.”

Blessed be the Lord, the God of Israel, From everlasting to everlasting! Then all the people said, “Amen,” and praised the Lord.

and four thousand were gatekeepers, and four thousand were praising the Lord with the instruments which David made for giving praise.

They are to stand every morning to thank and to praise the Lord, and likewise at evening,

Now therefore, our God, we thank You, and praise Your glorious name.
