PROLOGUE — Even War Stands Under Regulation
Deuteronomy 20 addresses the regulations of conducting war. Remarkably, this chapter is not filled with a merciless command to conquest, but with strikingly careful, humane provisions — accommodation for fear, an offer of peace, and even protection of the environment.
ACT ONE — Fear Not, for God Is With You (verses 1–4)
“When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them: for the LORD thy God is with thee, which brought thee up out of the land of Egypt… And the priest shall speak unto the people, and shall say unto them, Hear, O Israel, ye approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them; For the LORD your God is he that goeth with you.”

Fear not… for He goes with you. Before battle, the priest himself stood before the people and proclaimed courage — Israel’s true strength was never military power, but God’s presence.
ACT TWO — Those Exempted From War (verses 5–9)
The most surprising and humane portion of this chapter follows.
“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. And what man is he that hath planted a vineyard, and hath not yet eaten of it?… 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.”
A new house… a vineyard… a betrothed wife. Exemption from war was granted to those who had not yet completed three important beginnings of life — a home, a livelihood, a marriage. This was a remarkable act of respecting significant personal life moments over the nation’s need.
And an even more astonishing exemption follows.
“And what man is there that is fearful and fainthearted? let him go and return unto his house, lest his brethren’s heart faint as well as his heart.”
Whoever is fearful and fainthearted. Even someone who simply felt afraid was granted the right to return — not only for the practical reason that low morale could spread, but also out of respect for a person’s own psychological state.
ACT THREE — Two Different Principles for Treating Cities (verses 10–20)
The final part of this chapter presents the principle that peace must always be offered before attacking a city.
“When thou comest nigh unto a city to fight against it, then proclaim peace unto it. And it shall be, if it make thee answer of peace, and open unto thee, then it shall be, that all the people that is found therein shall be tributaries unto thee, and they shall serve thee.”
But for certain nations within the land of Canaan itself, this peace option was excluded — the principle of complete destruction already addressed in Deuteronomy 7 is reaffirmed. This chapter unusually closes with environmental consideration.
“When thou shalt besiege a city a long time… thou shalt not destroy the trees thereof by forcing an axe against them… for is the tree of the field man, that it should be besieged of thee?”
Is the tree of the field man? This remarkable question shows that even the destruction of war must never be unlimited. Fruit trees were a future food resource, and had to be preserved regardless of the outcome of the war.
REFLECTION — Humanity Preserved Even Amid Strength
The remarkable insight Deuteronomy 20 gives us is that even in the harshest circumstance of war, human consideration and wisdom were never entirely erased. Acknowledging fear, respecting significant life moments, and preserving resources for the next generation — all of this was required, even in the very midst of battle.
Even in the fiercest battles of your own life, do you preserve human consideration and wisdom for the future?
