5 And the officers shall speak unto the people, saying, What man is there that hath built a new house, and hath not dedicated it? let him go and return to his house, lest he die in the battle, and another man dedicate it. 6 And what man is there that hath planted a vineyard, and hath not used the fruit thereof? let him go and return unto his house, lest he die in the battle, and another man use the fruit thereof. 7 And what man is there that hath betrothed a wife, and hath not taken her? let him go and return unto his house, lest he die in the battle, and another man take her. 8 And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and faint-hearted? let him go and return unto his house, lest his brethren's heart 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.
