And the Levites are to stand in the morning to give thanks, and to sing praises to the Lord: and in like manner in the evening,

and to stand, morning by morning, to give thanks, and to give praise to Jehovah, and so at evening;

They had to take their places every morning to give praise and make melody to the Lord, and in the same way at evening;

Yet truly, the Levites shall stand to confess and to sing to the Lord, in the morning, and similarly in the evening,

To stand every morning - At the offering of the morning and evening sacrifice, they sounded their musical instruments, and sang praises to God.

And to stand every morning to thank and praise the Lord,.... The office of others of them was to sing the praises of God, both vocally and with instruments of music, at the time of the morning sacrifice:
and likewise at even; at the time of the evening sacrifice, by way of thankfulness for the mercies of the night and of the day.

"On each morning and evening to praise the Lord with song and instruments." These words refer to the duties of the singers and musicians, whose classes and orders are enumerated in 1 Chron 25. The referring of them to the Levites who assisted the priests in the sacrificial worship (Berth.) needs no serious refutation, for וּלהלּל הודות is the standing phrase for the sacred temple music; and we can hardly believe that the Levites sang psalms or played on harps or lutes while the beasts for sacrifices were slaughtered and skinned, or the meat-offerings baked, or such duties performed.

Morning and even - The two solemn times of offering sacrifices: which work was attended with publick prayer and thanksgiving.
