10:12 Be of good courage, and let us play the men for {e} our people, and for the cities of our God: and the LORD do that which seemeth him good.

(e) Here it is declared why war should be undertaken: for the defence of true religion and God's people.

10:6-14 They that are at war with the Son of David, not only give the provocation, but begin the war. God has forces to send against those that set his wrath at defiance, Isa 5:19, which will convince them that none ever hardened his heart against God, and prospered. Christ's soldiers should strengthen one another's hands in their spiritual warfare. Let nothing be wanting in us, whatever the success be. When we make conscience of doing our duty, we may, with satisfaction, leave the event with God, assuredly hoping for his salvation in his own way and time.
