1 Chronicles 23:24

Verse 1 Chronicles 23:24. Twenty years and upward.] It appears that this was a different ordinance from that mentioned 1 Chronicles 23:3. At first he appointed the Levites to serve from thirty years and upward; now from twenty years. These were David's last orders; see 1 Chronicles 23:27. They should begin at an earlier age, and continue later.

This was not a very painful task; the ark being now fixed, and the Levites very numerous, there could be no drudgery.
