The twelve officials supply Solomon with provisions (1 Kings 4:27-4:28)

“Those twelve officials supplied provisions for King Solomon, and for all who came to King Solomon’s table, each one in his month. They let nothing be lacking. They also brought to the required place barley and straw for the horses and the swift steeds, each according to his charge.”

Now we find out where all the provisions were coming from. Those 12 officials during 1 month of the year had to provide daily provisions for the king and his retinue. They also had to provide for those 40,000 horses which is a lot of horses to feed.
