'Sum' in the Bible

And David said to Joab and to the princes of the people, Go, number Israel from Beer-sheba even to Dan; and bring me word, that I may know the sum of them.

And Joab gave up the sum of the numbering of the people unto David. And all they of Israel were a thousand thousand and a hundred thousand men that drew sword: and Judah was four hundred threescore and ten thousand men that drew sword.
