2Co 6:17 GW The Lord says, “Get away from unbelievers. Separate yourselves from them. Have nothing to do with anything unclean. Then I will welcome you.”
2Co 6:17 (modified) The Lord says, “Get away from unbelievers. Separate yourselves from them. Have no contact with the unclean. Then I will welcome you.”
Referencing the unbelievers as “the unclean” infers that they are to be treated as though they have a contagious disease; like lepers in the Old Testament.
