3 and shall say to them, 'Hear, O Israel, today you are drawing near for battle against your enemies: let not your heart faint. Do not fear or panic or be in dread of them, 4 for the Lord your God is he who goes with you to fight for you against your enemies, to give you the 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.
