The close of our chapter contains the principles which were to govern Israel in their warfare. They were most carefully to discriminate between the cities which were very far off from them and those that pertained to the seven judged nations. To the former, they were, in the first place, to make overtures of peace; with the latter, on the contrary, they were to make no terms whatever. "When thou comest nigh unto a city _to fight against it_, then _proclaim peace_ unto it"--a marvelous method of fighting!--"And it shall be, if it make thee answer of peace, and open unto thee, then it shall be that all the people that is found therein shall be tributaries unto thee, and they shall serve thee. And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it; and when the Lord thy God hath delivered it into thine hands, thou shalt smite every male thereof"--as expressing the positive energy of evil--"with the edge of the sword. But the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof"--all that was capable of being turned to account in the service of God and of His people--"thou shalt take unto thyself; and thou shalt eat the spoil of thine enemies, which the Lord thy God hath given thee. Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations." Indiscriminate slaughter and wholesale destruction formed no part of Israel's business. If any cities were disposed to accept the proffered terms of peace, they were to have the privilege of becoming tributaries to the people of God; and in reference to those cities which would make no peace, all within their walls which could be made use of was to be reserved. There are things in nature and things of earth which are capable of being used for God--they are sanctified by the Word of God and prayer. We are told to make to ourselves friends of the mammon of unrighteousness, that when we fail, they may receive us into everlasting habitations; which simply means that if this world's riches come into the Christian's hands, he should diligently and faithfully use them in the service of Christ; he should freely distribute them to the poor, and to all the Lord's needy workmen; in short, he should make them available, in every right and prudent way, for the furtherance of the Lord's work in every department. In this way, the very riches which else might crumble into dust in their hands, or prove to be as rust on their souls, shall produce precious fruit that shall serve to minister an abundant entrance into the everlasting kingdom of our Lord and Saviour Jesus Christ.
