The attitude of the swine-like teacher is so contagious it is dangerous. God says we should not even 'touch their dead bodies' . This is a riddle in Hebrew that says we should not be 'joined to their foolishness nor plagued by it.' God is talking about teachers, not swine.
He may brag he gave an apple to a homeless guy. The next swine brags he gave two apples. The first responds that his was the only apple he had and he gave it.
This bragging of works is contagious. Do not be joined to it.
The swine will also make you feel bad for not having given any apples. The noodles you gave are not nearly as good.
Swine attitudes of self-righteousness based on his own ideas are contagious because they appeal to our flesh. We want to be noticed and appreciated. We want to look good to others. Do not be plagued by it.Have nothing to do with the swine or you may get caught up in their folly. Perhaps this is a source for Paul's teaching: 2Co 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
- Le 11:8 Of their flesh shall ye not eat, and their carcase shall ye not touch; they [are] unclean to you.
