Here is what I have gathered so far:

What does it mean to “not throw your pearls before swine”?

What are “your pearls”?
Who/What are swine?

Do not give what is holy to dogs, and do not throw your pearls before swine, or they will trample them under their feet, and turn and tear you to pieces. (Matthew 7:6)

We see dogs and swine are comparable. What are the traits of these two things?

A dog is someone who is a spiritual predator who feeds off of others & a swine we see in scripture is an unclean and abominable creature only worthy of housing demons and being thrown into the sea.

Could it be this scripture is saying do not gift someone the knowledge of what is holy (set apart) with anyone who is lawless, reprobate, unrepentant, and looking to feed off of and destroy you and your faith?

Ephesians 5:11 says “And have no fellowship with the unfruitful works of darkness, but rather reprove (expose) them”. We are to prove wrong their works; meaning doing so would bring conviction to them and expose their sin.

Perhaps, we aren’t to share even the beautiful commandments & ways of Yahuah with anyone who is reprobate and unrepentant, because all they will do is hate you and persecute you; seeking to destroy you. Does this person show the fruit worthy of repentance? Are they in the house of Yahuah?
