1 Chronicles 27:3KJV·traditional attribution
Of the children of Perez was the chief of all the captains of the host for the first month.
Matthew Henry Presbyterian
We have here an account of the regulation of the militia of the kingdom. David was himself a man of war, and had done great things with the sword; he had brought into the field great armies. Now here we are told how he marshalled them when God had given him rest from all his enemies.
