Joab gave up the sum of the numbering of the people to David. All those of Israel were one million one hundred thousand men who drew sword: and in Judah were four hundred seventy thousand men who drew sword.
"Perhaps the one thing that impresses more than David’s sins in his life are his repentances (cf. 2 Samuel 12:13 ff., and, associated in its heading with the same incident, Psalms 51). We do well to let his willingness to come fully to terms with his deficiencies inform our own responses to our moral failures before God." [Note: McConville, p. 71.]
