Deuteronomy 20:12 Meaning and Explanation
“And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it:”
King James Version (KJV)
Read this verse in context with translation switching:
Read Full Chapter →Ancient warfare rarely began with an offer. Moses places one here, and this verse describes what happens when that offer is turned down. Readers who wonder whether Israel's campaigns were simply conquest for its own sake will find a legal restraint written into the law itself: siege follows refusal, and refusal has to come first.
Israel's siege of a distant city was authorized only after that city refused the offered terms of peace and chose armed resistance. War became lawful once negotiation had been genuinely tried and rejected.
The Context of Deuteronomy 20:12
Moses is instructing Israel on the plains of Moab, shortly before the nation crosses the Jordan. Deuteronomy 20 gathers rules for war: the priest encourages the troops (verses 2-4), officers release men with unfinished houses, vineyards, betrothals, or fearful hearts (verses 5-8), and captains are appointed (verse 9). Verse 10 requires a proclamation of peace to any city approached in battle. Verse 11 covers a city that accepts. Verse 12 covers the alternative, and verses 13-15 describe how a besieged distant city is handled once the LORD delivers it.
What Does Deuteronomy 20:12 Mean?
The sentence opens with a condition, 'if it will make no peace with thee.' Everything that follows depends on the city's own answer. The KJV doubles the description of that answer: the city declines terms and then 'will make war against thee.' Both halves are active choices by the people inside the walls. Only after that double refusal does the command arrive, and it arrives as a single short clause: 'then thou shalt besiege it.' The colon at the end leaves the sentence unfinished, handing the reader on to verse 13, where the outcome depends on the LORD delivering the city into Israel's hands.
Within the chapter, verse 12 is the hinge between two very different outcomes. A city that opens its gates lives and serves (verse 11); a city that answers with war faces siege. Verses 15-18 then distinguish these far-off cities from the Canaanite cities inside the promised inheritance, which were under a separate and much stricter command tied to their worship practices. Israel had no standing permission to attack whoever it pleased. The law fenced war in with an offer of terms, a category of permitted targets, and even a rule protecting fruit trees during a long siege (verses 19-20).
The order of events here has a long echo in Scripture. God repeatedly sends word before He sends judgment: Jonah walks through Nineveh, prophets stand in city gates, and the offer of peace precedes the consequence. Jesus takes up the same picture in Luke 14:31-32, where a king facing a stronger army sends an embassy asking conditions of peace, and He weeps over Jerusalem for missing the things that belonged to her peace (Luke 19:41-42). Paul later speaks of God making peace through the blood of the cross and of ambassadors who plead with people to be reconciled. Peace offered first remains the pattern.
Deuteronomy 20:12 in the Original Language
tsur (צוּר), 'besiege' -- to bind in or hem about. The Hebrew pictures an army enclosing a city so that nothing passes in or out, a slow pressure meant to force surrender. The same root lies behind ordinary words for binding something up tightly.

Where Deuteronomy 20:12 Echoes in Scripture
Luke 14:31-32 gives this law a striking afterlife. Jesus asks what king, going to war against another with twice his numbers, fails to sit down first and consider whether he can meet him, and if he cannot, sends an ambassage while the other is still a great way off, desiring conditions of peace. The scene assumes exactly the procedure of Deuteronomy 20, and Jesus uses it to press the cost of following Him.
How to Apply Deuteronomy 20:12 Today
Few of us command armies, and the sequence in this verse still shapes ordinary conflict. Terms come before force. Before we escalate a dispute with a neighbor, a coworker, or a family member, we can ask whether an honest offer of peace has actually been made and heard. Offering peace costs something; it means naming what we are willing to give up. When the offer is refused, this law still limits the response, and later Scripture presses that limit further by asking us to live peaceably with all as far as it depends on us.
Reflection & Prayer
Where in our lives have we skipped straight to the siege? Is there someone we have written off before ever proclaiming peace to them? Father, You offered terms to us long before we deserved them. Teach us to make the first move toward peace, to mean it, and to leave the outcome in Your hands when it is refused. Amen.
