23:24 These [were] the sons of Levi after the house of their fathers; [even] the chief of the fathers, as they were counted by number of names by their polls, that did the work for the service of the house of the LORD, from the age of {e} twenty years and upward.
(e) David chose the Levites twice, first at the age of thirty as in 1Ch 23:3 and again afterward at twenty as the office required: at the beginning they had no charge in the temple before they were twenty-five years old, and had none after fifty, Nu 4:3.
23:24 Twenty years - As the Levites were anciently numbered from two several times, from the twenty fifth year of their age, and from the thirtieth, Numb 4:3 8:24. In like manner they are here numbered both from their twentieth year, when they were solemnly prepared for, and instructed, and by degrees exercised in some parts of their work; and from their thirtieth year, when they were admitted to the full exercise of their office. And the reason why they were now sooner admitted to service than they had been formerly, is given in the next verse s because now their work was more easy, being wholly discharged from that burdensome work of carrying the tabernacle. Besides the people of Israel were multiplied: therefore more hands were necessary, that every Israelite who brought an offering, might find a Levite ready to assist him.
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.
