23:28 Because their office [was] to wait on the sons of Aaron for the service of the house of the LORD, in the courts, and in the chambers, and in the {f} purifying of all holy things, and the work of the service of the house of God;
(f) In washing and cleansing all the holy vessels.
23:28 Holy things - Holy places, and garments, and vessels, and sacrifices, which were to be washed and cleansed from any filthiness that might cleave to them.
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.
