Joshua 9:20 explains why the leaders of Israel chose to spare the Gibeonites even after learning those people had tricked them. The leaders decided that the oath they had sworn in God’s name was binding, and breaking it would bring divine anger on the whole nation. The words are spoken by the princes (the tribal leaders) of Israel, and they are addressed to the wider congregation, who were angry that the Gibeonites had been spared.
We will do this to them, and let them live; lest wrath be on us, because of the oath which we swore to them.”

What Joshua 9:20 Means
The phrase “We will do this to them, and let them live” shows the leaders choosing a course they did not like but felt bound to follow. The Gibeonites had pretended to come from a distant land so that Israel would make a treaty with them, and the leaders had sworn an oath to them before checking the truth. Now they faced a choice between a dishonest alliance and a broken promise, and they chose to honor the oath.
The second half, “lest wrath be on us, because of the oath which we swore to them,” reveals their reasoning. They believed that breaking an oath sworn by the LORD would invite His displeasure on Israel. The verse does not promise that keeping promises will always bring blessing or that God approves of every outcome. It records a decision made in a specific moment, with a sense of accountability to God for words spoken in His name.
The Context of Joshua 9:20
The book of Joshua tells the story of Israel entering and settling the land of Canaan after the death of Moses. Traditionally its authorship is credited to Joshua himself, with later editing that many scholars attribute to a writer or editors who compiled the historical record. Its first readers were the Israelites, who needed to understand how their ancestors had taken the land and how they were to live faithfully within it.
Verses 17 through 23 show what follows the oath. The Israelites discover the Gibeonites are neighbors, not distant travelers, and they do not attack them, while the congregation complains. Verse 20 sits in the middle of that tension. Joshua then confronts the Gibeonites and assigns them to labor as woodcutters and water carriers for the community and the sanctuary. Reading the verse alongside this scene shows that the leaders’ decision was costly and still came with consequences for the deceivers.

A Short Prayer From Joshua 9:20
Lord, you see the promises I have made, both the ones I keep easily and the ones that now feel heavy. Help me to take my words seriously, especially when circumstances change or someone has not been fully honest with me. Give me wisdom to know when to hold firm and when to seek your guidance, and let my faithfulness reflect your own steadfast character. Teach me to trust you with the outcomes I cannot control. Amen.
