Keep away from everything impure

Deuteronomy 23:1-14

No one who has been emasculated by crushing or cutting may enter the assembly of the Lord.

No one born of a forbidden marriage nor any of their descendants may enter the assembly of the Lord, not even in the tenth generation.

No Ammonite or Moabite or any of their descendants may enter the assembly of the Lord, not even in the tenth generation.

Do not despise an Edomite, for the Edomites are related to you. Do not despise an Egyptian, because you resided as foreigners in their country. The third generation of children born to them may enter the assembly of the Lord.

When you are encamped against your enemies, keep away from everything impure.

Designate a place outside the camp where you can go to relieve yourself.  For the Lord your God moves about in your camp to protect you and to deliver your enemies to you. Your camp must be holy, so that he will not see among you anything indecent and turn away from you.

Member of the congregation;  The Lord's community is both inclusive and exclusive. It is marked by purity and holiness.

Why?

God is holy so his people's identity, living style, and environment have to keep away from everything impure.

A forbidden marriage not any of their descendants enter the assembly of the Lord is asking God's people has a good marriage. Keep the society under correct custom.

How?

My God is Holy so I have to Hoty either. Keep away from everything impure.
