I Chronicles 23:1,4-6

I Chronicles 23:1,4-6, So when David was old and full of days, he made Solomon his son king over Israel. And he gathered together all the princes of Israel, with the priests and the Levites. Of which, twenty and four thousand were to set forward the work of the house of the LORD; and six thousand were officers and judges: Moreover four thousand were porters; and four thousand praised the LORD with the instruments which I made, said David, to praise therewith. And David divided them into courses among the sons of Levi … King David was an army general and he was great at organization. He had his army organized with captains over hundreds and leaders over them. David organized the priests by course. He had 24 different courses so that each priest served about two weeks each year. The priests weren’t lazy, they had much preparation for that two week duty. They were like our astronauts who prepare for years just for a two week space shuttle mission. David organized the porters, who were the doorkeepers at the Temple-to-be. David had traveling judges to settle disputes around the country. And, Because David himself was a musician, David appointed singers and instrument players to make music before the Lord.  God was pleased with David’s organization. David made sure that everything ran smoothly at God’s house.
