Deuteronomy 1:30

Where you were weak, dispirited, divided, raw, and unexperienced, and in a great measure unarmed, and able to do nothing against your numerous, potent, united enemies, but to stand still and see the salvation of God. And therefore now your distrust is highly unreasonable, when you have been hardened and fitted for military service by your travels, disciplined and experienced in some degree as to martial affairs, encouraged by frequent and glorious miracles for forty years together, and you are going into a country divided into several nations and kingdoms.
