Joshua 10-12

"For it was of the LORD to harden their hearts, that they should come against Israel in battle, that He might utterly destroy them, and that they might receive no mercy, but that He might destroy them, as the LORD had commanded Moses" - Joshua 11:20.

Canaanites attack the Gibeonites, for surrendering to Israel.  Gibeon appeals to Israel for help and Israel defeats 5 kings at once (Jerusalem is one). Joshua asks God to make the sun and moon stand still, so he has more time to defeat them all, and God does it. Joshua makes a public example of the 5 kings, to encourage Israel in their mission. Israel also conquers all of Canaan, except some Anakim in Gaza and Gath (Goliath's town).  They came out to fight Israel.  Chapter 12 lists kings and peoples conquered.

How this is about Jesus
He commands nature to defeat evil forces, too (Mark 4:35-41).

He conquers kings that fight against Him (Psalm 2:8-12).

Application

• It is interesting how similar to ISIS beheading videos Joshua 10:22-26 is.  God did approve Joshua doing it, but it is a brutal atrocity without God's warrant.
• Today we conquer the land by conversion, not killing.
