Horses, and chariots - The most formidable elements of an Oriental host, which the Canaanites possessed in great numbers; compare Joshua 17:16; Judges 4:3; 1 Samuel 13:5. Israel could not match these with corresponding forces (compare Deuteronomy 17:16 note and references), but, having the God of battles on its side, was not to be dismayed by them; the assumption being that the war had the sanction of God, and was consequently just.

When thou goest out to battle - This refers chiefly to the battles they were to have with the Canaanites, in order to get possession of the promised land; for it cannot be considered to apply to any wars which they might have with the surrounding nations for political reasons, as the Divine assistance could not be expected in wars which were not undertaken by the Divine command.

When thou goest out to battle against thine enemies,.... There were two sorts of war the Israelites were engaged in, one commanded and another permitted, as Maimonides (c) distinguishes; one was by the order and appointment of God, as against the seven nations of Canaan; the other was voluntary and arbitrary, which was left to their own discretion and will, as they saw fit, when they were provoked or distressed, or were invaded by their enemies, or they saw reason to go out against them, and either act the offensive or defensive part, or both; and of each of these some things are said in this chapter:

and seest horses and chariots, and a people more than thou; the Israelites had no horses, and so no chariots, their armies were all infantry; but their neighbouring nations that made war with them had a large cavalry, and multitudes of chariots, which made them very formidable; thus Shishak, king of Egypt, in the times of Rehoboam, came against Jerusalem with 1200 chariots and 60,000, horsemen, and people without number; and Zerah the Ethiopian, in the times of Asa, came against him with an host of 100,000 men, and three hundred chariots, 2 Chronicles 12:2.

be not afraid of them; because of the strength of their cavalry, the terrible approaches of their chariots, and the number of their men:

for the Lord thy God is with thee; hence, as Hezekiah says, more would be with them than with their enemies, with whom was an arm of flesh, but with them the Lord their God, 2 Chronicles 32:7 and so the Targum of Jonathan,"for all of them shall be reckoned as one horse and one chariot before the Lord your God;''with whom numbers are nothing; and which adds,"for his Word shall be your help;''the eternal Logos, or Word of God; so Onkelos; and if God and his Word, his only begotten Son, are on the side of his people, they have nothing to fear from enemies, though ever so many and mighty:

which brought thee out of the land of Egypt; which is observed for the encouragement of their faith and confidence in him; for he that did that for them, what is it he cannot or will not do?

(c) Hilchot Melachim, c. 7. sect. 1.

Instructions Relating to Military Service. - If the Israelites went out to battle against their foes, and saw horses and chariots, a people more numerous than they were, they were not to be afraid, because Jehovah their God was with them. Horses and chariots constituted the principal strength of the enemies round about Israel; not of the Egyptians only (Exodus 14:7), and of the Canaanites and Philistines (Joshua 17:16; Judges 4:3; 1 Samuel 13:5), but of the Syrians also (2 Samuel 8:4; 1 Chronicles 18:4; 1 Chronicles 19:18; cf. Psalm 20:8).

When {a} thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them: for the LORD thy God is with thee, which brought thee up out of the land of Egypt.

(a) Meaning, upon just occasion: for God does not permit his people to fight every time it seems good to them.

CHAPTER 20

De 20:1-20. The Priests' Exhortation to Encourage the People to Battle.

1. When thou goest out to battle against thine enemies-In the approaching invasion of Canaan, or in any just and defensive war, the Israelites had reason to expect the presence and favor of God.

20:1-9 In the wars wherein Israel engaged according to the will of God, they might expect the Divine assistance. The Lord was to be their only confidence. In these respects they were types of the Christian's warfare. Those unwilling to fight, must be sent away. The unwillingness might arise from a man's outward condition. God would not be served by men forced against their will. Thy people shall be willing, Ps 110:3. In running the Christian race, and fighting the good fight of faith, we must lay aside all that would make us unwilling. If a man's unwillingness rose from weakness and fear, he had leave to return from the war. The reason here given is, lest his brethren's heart fail as well as his heart. We must take heed that we fear not with the fear of them that are afraid, Isa 8:12.
