Deuteronomy 23:14b Your camp must be holy, so that He will not see among you anything indecent and turn away from you. (Because the Lord had promised to be present with His people when they fought against the enemy inhabitants of the Promised Land, in the same way the Tabernacle and the Ark of the Covenant had to be holy through cleansing and appropriate rituals and because they represented God's very presence in the camp, the camp itself had to be sanitary and uncontaminated as well. The meaning behind the term anything indecent refers to nakedness and shameful disgracefulness associated with a word or a thing.
Not only were the people to dispose of body wastes appropriately
so their body functions would not contaminate the campsite and so they themselves would be ritually pure,
they were also to keep their minds pure and uncontaminated.
Since the Lord was present with them in their camp, they were to guard against anything that would shame them in the Lord's presence.
Failure to keep themselves decent and holy
meant that the Lord would turn away from them and leave them vulnerable to defeat from their enemy.
Today, the Lord calls us to that same care in both our physical holiness and in our thoughts and attitudes.
When we fail to uphold the Lord's command to keep ourselves pure,
we are choosing to set ourselves apart from the Lord's presence
and from His promise to give us victory over our enemy.
Since the Lord is present in us, we honor Him with a clean heart and a clean mind, arming ourselves against impure thoughts and attitudes and actions.)
