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 Chronicles 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.

And to stand every morning to thank and praise the LORD, and likewise at even:

23:30 Morning and even - The two solemn times of offering sacrifices: which work was attended with publick prayer and thanksgiving.

23:24-32 Now the people of Israel were so many, there should be more employed in the temple service, that every Israelite who brought an offering might find a Levite ready to help him. When more work is to be done, it is pity but there should be more workmen. A new heart, a spiritual mind, which delights greatly in God's commandments, and can find a refreshing feast in his ordinances, forms the great distinction between the true Christian and all other men in the world. To the spiritual man every service will yield satisfaction. He will be ever abounding in the work of the Lord; being never so happy as when employed for such a good Master, in so pleasant a service. He will not regard whether he is called to take the lead, or to keep the charge of others who are placed over him. May we seek and serve the Lord uprightly, and leave all the rest to his disposal, by faith in his word.
