From twenty years old and upward, all that are able to go forth to war in Israel: you and Aaron shall number them by their armies.
By this census all the young men of Israel were urged to the consideration of a possible claim upon them. It is to the young men that a country looks when her integrity and liberties are in danger. Young men are wanted still to take a brave and intelligent part in the strife of the Church militant. "I have written unto you young men because ye are strong, and the word of God abideth in you, and ye have overcome the wicked one." So Paul to Timothy: "Endure hardness, as a good soldier of Jesus Christ." God's people have to deal with the Canaanites, Amorites, and all the rest of the hostile nations. Many iniquities are in possession of the earth. Old men, who have struggled against them and done something to diminish them, ask who will take up the sword and shield and go forth against the mighty. The word comes to us. "You are fit to fight. Will you fight?" Young men dazzled with the visions of military glory, here is a campaign where not men are slaughtered, but the evils that ruin men. Our Lord, the Captain of our salvation, will richly equip us with weapons mighty for the pulling down of strongholds, the armour of righteousness on the right hand and the left. - Y.
