5 Then the officials shall address the troops, saying, "Has anyone built a new house but not dedicated it? He should go back to his house, or he might die in the battle and another dedicate it. 6 Has anyone planted a vineyard but not yet enjoyed its fruit? He should go back to his house, or he might die in the battle and another be first to enjoy its fruit. 7 Has anyone become engaged to a woman but not yet married her? He should go back to his house, or he might die in the battle and another marry her." 8 The officials shall continue to address the troops, saying, "Is anyone afraid or disheartened? He should go back to his house, or he might cause the heart of his comrades to melt like his own."
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.
