“David did not count those below twenty years of age, for the LORD had promised to make Israel as many as the stars of heaven” (v23). The Lord had given King David plenty of men for military service. There were famous “mighty men” like Benaiah and thousands of others who gave one month a year (v1) for national service. Some took charge of the king’s fields, flocks, and properties (v25-34). God did not want David to obsessively count this great, blessed people (a disaster – v24), but simply to be thankful.
“This is the number of the people of Israel …” (v1). Everything in our world, including us, belongs to God. We can trust Him to abundantly supply what we need.
