20:1 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.
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.
