5 Then the officers shall speak to the people, saying, 'What man is there that has built a new house and has not dedicated it? Let him go back to his house, lest he die in the battle and another man dedicate it. 6 And what man is there that has planted a vineyard and has not enjoyed its fruit? Let him go back to his house, lest he die in the battle and another man enjoy its fruit. 7 And what man is there that has betrothed a wife and has not taken her? Let him go back to his house, lest he die in the battle and another man take her.' 8 And the officers shall speak further to the people, and say, 'What man is there that is fearful and fainthearted? Let him go back to his house, lest the heart of his fellows melt as his heart.'
Matthew Henry's Commentary on Deuteronomy 20:5-8
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.
