Devoted To Destruction

[ESVi] Josh. 11:20 For it was the LORD’s doing to harden their hearts that they should come against Israel in battle, in order that they should be devoted to destruction and should receive no mercy but be destroyed, just as the LORD commanded Moses.

For their wickedness the inhabitants of the promised land were destroyed. This will play out again when Jesus returns. All His enemies will be subdued and bow.
From His mouth will come a sword which will slay His enemies and give life to His friends. The word judges. The first time He came for all the world. Next time He comes for all those who said yes to mercy and grace.
His word endures forever.
