Purity was to be a high-priority for the people of God – in every area of their lives. There was no place or potential circumstance where the pursuit of holiness was either unnecessary or failed to apply. And as we’ll see in Deuteronomy 23:9-14, even the front lines of battle were to be considered holy unto the Lord. These verses provide the men of Israel with God’s clear instructions regarding times of war. When they were called to assemble for battle, they were to remember their status as God’s chosen people – set apart for His glory and tasked with honoring His holy name. And, as always, God gets very specific, providing them with detailed instructions regarding their personal holiness and hygiene during wartime. The battlefield was not to be used an excuse for spiritual apathy or moral laxness. The priority of personal and corporate holiness took precedence over everything, including war.
