After the revelation of the Ten Commandments at Mt. Sinai, Moses and Joshua climb the mountain. From below, they hear the sound of people worshiping an idol, the Golden Calf. Joshua says, “The sound of war is in the camp!” (Exodus 32:17). “No,” replies Moses, “That’s the sound of people singing.”
When Moses asks God for help with spiritual leadership, God gifts 70 people with the ability to prophesy. When a young servant reports to Moses and Joshua that people are prophesying in the camp, Joshua says, “Jail them!” (Numbers 11:28). “Don’t,” replies Moses, “If only all God’s people could be prophets!”
When the twelve scouts return from assessing the habitability of Canaan, ten scouts report that fearsome giants control the land. But scouts Joshua and Caleb say, “Don’t be afraid if they fight us; they are undefended!” (Numbers 14:9)
If the Torah were a movie, those three lines would convey Joshua’s character. His eyes see the discipline of war everywhere. So it’s no surprise that in the sequel (i.e., the next book of the Bible)
The Book of
Joshua, he leads the people to war.
The Biblical Joshua is no ordinary general. He is a deeply spiritual person. He has a gift for creating ritual, which he uses to design a ceremony for crossing the Jordan River (Joshua 3:1-17). He facilitates miracles: when he asks God to make the sun stand still, God complies (Joshua 10:12-14). He is a stickler for the ethics of just conduct in war, punishing soldiers who violate them (Joshua 7:1-26). Perhaps a spiritual frame helps him shape and contain war’s terrifying adrenaline overload.
But peace is not part of Joshua’s spirituality. He accepts a peace treaty only when tricked into it (Joshua 9:1-27). He considers his war to be a holy war, commanded by God.
On these matters, he completely reverses the teaching of his mentor Moses. For Moses, a divine command to do battle should be questioned. A peace treaty should be offered, proactively.
