>>>Where does the empty wagon advocate kochi veotzem yodi?
It doesn’t use those words but does have the exact attitude the posuk
וְאָֽמַרְתָּ֖ בִּלְבָבֶ֑ךָ כֹּחִי֙ וְעֹ֣צֶם יָדִ֔י עָ֥שָׂה לִ֖י אֶת־הַחַ֥יִל
הַזֶּֽה
That is exactly the way The Empty Wagon describes the six day war. Keep Hashem out of the picture. The fact the Israeli were facing armies with more than three times the amount of soldier, tanks, airplanes, money and other equipment each .And in some cases more than five times the amount of Israeli resources ? No problem. Israeli ingenuity knows how to deal with that. Hashem helped? What? Where does Hashem come into the picture? It was all superior Israeli strength.
You can’t get more Kochey Votzem Yodey than that.
