Deuteronomy 20 is one of the most difficult chapters in the book because it addresses war. It must therefore be read slowly, historically, and theologically. The chapter is not a celebration of violence. It is a regulation of Israel’s warfare within a unique covenant setting, and it repeatedly turns the reader’s attention away from military pride toward fear of God, pastoral care for the fainthearted, and restraint even in siege.
For Orthodox Christians, this chapter is best approached with sobriety. The abiding fruit is not militancy, but discernment about fear, trust, and spiritual warfare. The Church never treats violence lightly. She also never denies that evil is real and must be resisted.
Deuteronomy 20 - War Fear and Trust in the Lord
Historical and Scriptural Context
Moses prepares Israel for conflict in the land. The chapter addresses battle fear, exemptions from combat, offers of peace for certain cities, and restraint regarding fruit trees during siege. The chapter belongs to a particular salvation-historical moment in which Israel is both nation and covenant people, and in which the preservation of the holy people has a unique redemptive significance.
Christian readers must therefore distinguish enduring principles from non-transferable historical form. The New Testament does not turn the Church into a conquering state. Instead, it shifts the central battle into the arena of faith, temptation, principalities, and the passions. Deuteronomy 20 is therefore not a charter for Christian militarism. It is a difficult witness from Israel’s national life that the Church receives with fear, historical honesty, and spiritual transposition.
Geographical Significance ⛰️
The chapter assumes roads, battlefields, vineyards, homes, and siegeworks in the land of promise. Even the note about fruit trees is geographical. War is not allowed to become a scorched-earth frenzy. The land is inheritance, provision, and future life. Israel may not destroy tomorrow’s nourishment in today’s panic.
Characters
- Moses: regulating fear and force before the crossing.
- The priest: speaking courage to the people before battle.
- The scribes or officers: dismissing those not ready for combat.
- The fearful man: not mocked, but sent home so fear does not spread.
- The Lord: the true deliverer who goes with His people.

1. Courage begins with remembrance
“And if thou shouldest go forth to war against thine enemies, and shouldest see horse, and rider, and a people more numerous than thyself; thou shalt not be afraid of them, for the Lord thy God is with thee, who brought thee up out of the land of Egypt. And it shall come to pass whenever thou shalt draw nigh to battle, that the priest shall draw nigh and speak to the people, and shall say to them, Hear, O Israel; ye are going this day to battle against your enemies: let not your heart faint, fear not, neither be confounded, neither turn aside from their face. For it is the Lord your God who advances with you, to fight with you against your enemies, and to save you.” (Deuteronomy 20:1-4, Brenton)
The answer to fear is not bravado. It is memory. “Who brought thee up out of the land of Egypt.” Past deliverance becomes present courage.
The priest speaks before the battle because fear is not merely military. It is spiritual. The heart must be steadied. Orthodox tradition carries this insight into every arena of struggle. Prayer before conflict is not weakness. It is realism. Yet the Church does not simply move from this text to blessing violence as spiritually pure. The later Orthodox tradition remains sobered by bloodshed even where war is treated as defensive necessity.
2. Human limits are acknowledged
“And the scribes shall speak to the people, saying, What man is he that has built a new house, and has not dedicated it? let him go and return to his house, lest he die in the war, and another man dedicate it. And what man is he that has planted a vineyard, and not been made merry with it? let him go and return to his house, lest he die in the battle, and another man be made merry with it. And what man is he that has betrothed a wife, and has not taken her? let him go and return to his house, lest he die in the battle, and another man take her. And the scribes shall speak further to the people, and say, What man is he that fears and is cowardly in his heart? Let him go and return to his house, lest he make the heart of his brother fail, as his own.” (Deuteronomy 20:5-8, Brenton)
These exemptions show that Israel’s war law is not built on the total absorption of the person into the machinery of battle. Household, vineyard, marriage, and even acknowledged fear matter. The fearful man is sent home not because he is despised, but because fear is contagious.
Spiritually, this is very perceptive. One anxious, panicked heart can weaken many others. Saint John Cassian and later ascetic writers know that thoughts spread, moods spread, and cowardice spreads. Vigilance includes knowing when a soul is unstable.
3. Peace is offered where appropriate
The chapter distinguishes between cities far away and the inheritance cities under judgment. That distinction belongs to Israel’s unique historical mission and should not be generalized carelessly. What is clear for Christian moral reflection is that war is not treated casually. Terms, order, and restraint all appear. Christian teaching must also say plainly that the Church does not carry forward Deuteronomy 20 as a standing political command. The old covenant’s warfare legislation belonged to Israel as a nation under a unique divine economy; the Church’s primary warfare is now baptismal, ascetical, and Eucharistic.
4. Even war does not abolish reverence for life
“And if thou shouldest besiege a city many days to prevail against it by war to take it, thou shalt not destroy its trees, by applying an iron tool to them, but thou shalt eat of it, and shalt not cut it down: Is the tree that is in the field a man, to enter before thee into the work of the siege? But the tree which thou knowest to be not fruit-bearing, this thou shalt destroy and cut down; and thou shalt construct a mound against the city, which makes war against thee, until it be delivered up.” (Deuteronomy 20:19-20, Brenton)
This is one of the chapter’s most revealing details. Even in siege, Israel is forbidden from reckless destruction. Fruit trees are future nourishment. Rage must not devour tomorrow.
Orthodox spiritual life has a close parallel. In battling sin, a person must not destroy what is good in created life. Ascetic struggle is not hatred of creation. It is the wise cutting away of what bears no good fruit.
5. From earthly war to spiritual warfare
The Fathers commonly redirect Israel’s battle imagery toward the struggle against passions, demons, and sin. Origen, though not an Orthodox Father in every respect, profoundly influenced later Christian habits of reading battle texts spiritually. Orthodox tradition more broadly receives the abiding warfare as one fought through prayer, fasting, courage, and faithfulness.
This is also where later Orthodox reception becomes important. Saint Athanasius, in his Letter to Amun, can speak of killing in war as different from murder in certain circumstances, especially in defense of the innocent. Yet Saint Basil’s Canon 13 still treats bloodshed with penitential seriousness, recommending temporary exclusion from communion for soldiers who have killed. Together they show the Orthodox instinct: the Church may acknowledge tragic necessity, but she never turns killing into an uncomplicated good.
Church’s Voice in Worship
The Church prays for peace repeatedly and seriously. This alone should shape how Deuteronomy 20 is taught. The chapter cannot be used to romanticize conflict. At the same time, Orthodox prayer also asks for courage, protection, and victory over visible and invisible enemies. In present Church practice, the deepest continuity with Deuteronomy 20 lies not in holy war, but in truthful fearlessness, disciplined restraint, intercession, and the struggle against the passions.
A direct lectionary placement should be verified before being asserted. The chapter’s strongest Orthodox use today is often spiritual and ascetical: trust in God, truthful naming of fear, and wise resistance to evil.
Spiritual Fruit 🍇
- Courage through remembrance: facing fear by recalling God’s past faithfulness.
- Humility about limits: admitting when a heart is not ready.
- Restraint: refusing totalizing destruction.
- Spiritual watchfulness: recognizing contagion of fear and thoughts.
- Peace-seeking seriousness: never treating conflict as entertainment.
Questions for reflection:
- What “horses and riders” make me feel small right now?
- Do I hide fear behind bravado?
- In fighting sin, do I sometimes damage what is good and fruitful?
Teacher's Notes
- This chapter requires careful framing. Stress its unique covenant-historical setting.
- Emphasize the priest’s speech and the exemptions. Both soften simplistic readings of biblical warfare.
- Fruit trees provide an important lesson in restraint and stewardship.
- A spiritual reading of warfare is legitimate and important, but it should not erase the original historical seriousness of the text.
- Athanasius’ Letter to Amun and Basil’s Canon 13 are especially important for showing that the Orthodox Church does not read war in triumphalist terms: even necessary fighting leaves a wound and is handled penitentially.
