A reading from the Book of Judges, the third chapter.
1 Now these are the nations that the Lord left, to test Israel by them, that is, all in Israel who had not experienced all the wars in Canaan. 2 It was only in order that the generations of the people of Israel might know war, to teach war to those who had not known it before. 3 These are the nations: the five lords of the Philistines and all the Canaanites and the Sidonians and the Hivites who lived on Mount Lebanon, from Mount Baal-hermon as far as Lebo-hamath. 4 They were for the testing of Israel, to know whether Israel would obey the commandments of the Lord, which he commanded their fathers by the hand of Moses. 5 So the people of Israel lived among the Canaanites, the Hittites, the Amorites, the Perizzites, the Hivites, and the Jebusites. 6 And their daughters they took to themselves for wives, and their own daughters they gave to their sons, and they served their gods. (Judges 3:1–6 ESV)
Why might Israel need to know war? Why might God need to know whether Israel will do as it is commanded?
God already knows Israel won’t. This is settled. Judges begins with this failure. God knows Israel will fail, will not fight and not separate itself and will, instead, subjugate and copulate with the people of Canaan. (You likely cannot have one without the other.) And worship their gods.
So, is war good for Israel? War is inescapable. As Israel intertwines itself with the people whose land they are settling, they will also be subjugated by those people. The wars Israel will fight will no longer be for conquest, but for survival and liberation. They will need rescuing, redeeming. War will be the instrument of their (all-too-regular) redemption. And so the rest Israel was given briefly at the end of Joshua’s leadership will remain a dream, a distant dream.
In this, I am reminded of the expulsion of Eden, when Adam is expelled from the Garden and the ground cursed. He shall have to sweat and work for his bread from a ground that once gave plenty with little or no work. He shall fight thorns and thistles, and for what? For uncertain daily bread. Fighting a ground for his sustenance he shall be buried in when he dies.
Some days will be good. And some will not.
And so, Israel struggles. Mostly against itself. Mostly against its sin. Against the consequences of its sin. God will continue to fight for Israel — the people of God were no more abandoned than were Adam and Eve. But God does not alter their condition any. War will be their lot, their struggle, their fate. For both subjugation and liberation. We will win, and we will lose.
A day will come when Israel will no longer need to learn war — Isaiah 2:4 promises that day will come — but it is not today. Today, we learn to fight.
Because without our will to fight, God cannot be in our midst.
