1 Chronicles 27:11
The eighth captain for the eighth month was Sibbecai the Hushathite, of the Zarhites: and in his course were twenty and four thousand. The eighth captain for the eighth month was Sibbecai the Hushathite, of the Zarhites: and in his course were twenty and four thousand.
1 Chronicles 27:11 stands in the account of the rest of David's reign, dealing with arrangements for the service of God's house or temple and the affairs of his kingdom. It names Sibbecai the Hushathite as the captain for the eighth month, with twenty-four thousand men in his course or division. Together with the surrounding list in 1 Chronicles 27:1-15, it shows the year divided into twelve months, each with its appointed captain and course, indicating that the Bible recognizes a twelve-month year.
The surrounding list presents David's regular army divisions, which may explain the difference between the army total in Chronicles and that in 2 Samuel 24:9, if the Chronicles census included the regular army while Samuel's account did not.
