1 Chronicles 5:22

Many Hagrites were killed because God helped the people of Reuben win the war. Then the tribes of Manasseh, Reuben, and Gad settled in the land of the Hagrites. They lived there until the time when the Israelites were taken into captivity.

Warrior, fighting under the banner of the Lord Jesus, observe this verse with holy joy, for as it was in the days of old so is it now. If the war be of God the victory is sure. The sons of Reuben, and the Gadites, and the half tribe of Manasseh could barely muster forty-five thousand fighting men, and yet in their war with the Hagarites, they slew a hundred thousand men for they cried to God in the battle and he help them, because they put their trust in him. The Lord saves not by many nor by few. It is ours to go forth in Jehovah's name even if we are but a handful of people, for the Lord of Hosts is with us as our Captain. The Isrealites did not neglect buckler, sword and bow, but they did not place their final trust in these weapons. We must use all fitting means, but our confidence must rest in the Lord alone, for he is the sword and the shield of his people. The great reason of their extraordinary success lay in the fact that "the war was God's." Beloved, in fighting with sin without and within, with errors either doctrinal or practical, with spiritual wickedness in high places or low places, with devils and the devil's allies, you are waging Jehovah's war. Unless God himself can be beaten, you need not fear defeat. Be unshaken before superior numbers, shrink not from difficulties or seeming impossibilities, flinch not at wounds or death, strike with the two-edged sword of the Spirit, and the slain shall lie in heaps. The battle is the Lord's and he will deliver his enemies into our hands. With steadfast foot, strong hand, dauntless heart, and flaming zeal, rush to the conflict, and the hosts of evil shall fly like chaff before the gale.

Stand up! stand up for Jesus! The strife will not be long; This day the noise of battle, The next the victor's song: To him that overcometh, A crown of life shall be; He with the King of glory Shall reign eternally.
