Then in Deuteronomy 20 comes in the law of battles. We have the utmost care taken that they should be in no way conformed to the Gentile license. The governing principle here, as elsewhere, is confidence in Jehovah, the God who had taken His people, brought them out of Egypt into relationship with Himself, and was now placing them in His own land. It would be beneath the honor of God that any should be forced to fight His battles. He would give His people in everything to think of Himself. It was not a question of soldiery or strategy, of force or skill or fraud, but of Jehovah their God. It is evident that no means could more thoroughly purge from those who were to engage in battle what was unworthy of such a God and of such a people.
It is referred to now as being not the least striking of the peculiarities of Deuteronomy, and it is obvious how it suits the case in every way. The heavenly land is for us the scene of contest with the enemy. There are no such laws of war in the other books of Moses; they are here only. The wilderness is the scene of temptation. Canaan is the place where the enemy must be fought and beaten. But there is no power by which he can be overcome but that of God. Consequently faint heartedness would be intolerable; for it could only arise from this – that the people were thinking not of Jehovah their God, but of themselves or their enemies. Impossible thus to win the battles of Jehovah. What secures victory is the certainty that our God calls to the fight, that it is His battle, not ours: where it is so, we are as sure of the end as of the beginning. We are calmly convinced that as He does not send us at our own charges, so further He who calls to fight will secure that the enemy shall be vanquished.
Hence it is that God lays down in the most minute manner His consideration for His people. In the case of a new house, or of one who had planted a vineyard or betrothed a wife, all is cared for: where fearfulness of heart prevailed, such are made to feel that they were unworthy to enter on the battles of Jehovah. Further, there is beautiful consideration on His part for the enemy; for when they came nigh the threatened city, they were first called to proclaim peace to it: a singular way of making war, but worthy of God. He took no pleasure in war, and would accustom His people to go forth, even were it to fight, remembering themselves “shod with the preparation of peace,” if I may so say. “And it shall be, if it [the city] 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 Jehovah thy God hath delivered it into thine hands, thou shalt smite every male thereof with the edge of the sword.” There is just as serious a dealing with them, in proportion to the reality with which the offer of peace had been made before. God’s ways are not as ours.
Further, “Thus shalt thou do unto all the cities which are very far off from thee.” There was one exception: there must be no peace with the Canaanites; not because they were dreaded as rivals, but doomed to destruction because of their abominations and seductions. It is well known that some find a difficulty in this. Possibly it may interest others, if it do not relieve the first of their difficulty, to know that, typically considered, the Canaanites represent the emissaries of Satan, the spiritual wickedness in heavenly places, those rulers of the darkness of this world with whom we are called to wrestle now. They are specifically the powers of evil which continually turn every link of religion into a means of deliberate and ruinous dishonor of God. With such there can be, there ought to be, no terms, no compromise, no cessation of the fight at any time or under any possible circumstances. This is the typical force of what is referred to here.
I may just add the further remark, that of all the nations on the face of the earth, there was no such hotbed for every kind of corruption among men, and for all wickedness and abomination in the sight of God, as the Canaanites whom God devoted to destruction. It was therefore perfectly just, as far as righteousness was concerned, to hold up these Canaanites for a solemn warning to all the world and to all times. If national righteousness was sought, if there was to be the honor of God maintained in Israel, they must be extirpated; and there were the wisest reasons for doing that work by the sword of Israel. In the last lecture we saw that, so far from passing over His own people, God never dealt with any nation with the same strictness as with Israel. We saw that every soul of Israel perished in the wilderness except the two spies who stood for God, even against their fellows as well as the multitude; and certainly, if God caused that all Israel should fall in the wilderness because of their sins, if He did not even spare the single fault of Moses which he himself records, where can men complain justly of – the doom that befell such corrupters of the race, sure above all to be the moral destroyers of Israel had they been spared? In fact the children of Israel had not the faith to destroy them as they ought; they had not therefore the fidelity according to God’s word to exterminate the Canaanites, and so much the worse for themselves; for they became the means of dragging Israel into abominations, and thus drew judgments down on them after no long time.
This then will suffice, I trust, to make plain the folly of distrusting scripture, and the wisdom of always setting to our seal that God is true, and that He is righteous. In short God is always good, true, wise, and right.
Remark another thing. When Israel did besiege a city, God skewed His care, even if it were only for a tree good for human food, binding it with His own hand on His people in the midst of that which proved His face set against the enemies of His glory in the world. Nevertheless He would not allow them even there to act without consideration where was any food fit for the use of man. “The trees which thou knowest that they be not trees for meat, thou shalt destroy and cut them down”; but in case of those that furnished food, it was absolutely forbidden. Such is God, acting in time as He counsels from eternity to eternity, but condescending to speak and to exercise the thoughts of His people about the smallest matters for this life.
