Joshua 11:18-20

Amplified Bible

¹⁸ Joshua waged war with all these kings ^[a]a long time [at least five years]. ¹⁹ There was no city that made peace with the Israelites except the Hivites living in Gibeon; they took all the others in battle. ²⁰ For it was [the purpose] of the Lord to harden their hearts, to meet Israel in battle so that Israel would utterly destroy them, that they would receive no mercy, but that Israel would destroy them, just as the Lord had commanded Moses.
