1 Chronicles 27:1, 23-24

This is the list of the Israelites who served the king in the army. Each division was on duty one month each year. There were leaders of families, commanders of a hundred men, commanders of a thousand men, and other officers. Each division had twenty-four thousand men.

The LORD had promised to make the Israelites as many as the stars in the sky. So David only counted the men who were twenty years old and older. Joab son of Zeruiah began to count the people, but he did not finish. God became angry with Israel for counting the people, so the number of the people was not put in the history book about King David’s rule.
