3 He will say to them, 'Listen to me, all you men of Israel! Do not be afraid as you go out to fight your enemies today! Do not lose heart or panic or tremble before them. 4 For the Lord your God is going with you! He will fight for you against your enemies, and he will give you victory!'
Matthew Henry's Commentary on Deuteronomy 20:3-4
Commentary on Deuteronomy 20:1-9
(Read Deuteronomy 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, Isaiah 8:12.
