There are a couple of things implied here in this verse: 1) Someone has told someone else something in confidence 2) The person who has been told can not contain themselves (keep the secret) and has to share it with everyone they meet.
In the first part of this verse, we can see the importance of choosing our confidants wisely. There are two types of folks who talk too much (the verse in Greek implies a babbler) those who ramble on with no ill or malice and those who gossip and spread rumors. The first friend may be an annoyance at times, the second, however, is a sinner Leviticus 19:16 and willing to be disloyal to us. We find in Proverbs 11:13 that a true friend will always keep the things told to them in confidence while a gossiper can’t wait (or help themselves from) to betray our confidence.
The second part of the verse makes it clear we are to have no part with (associate with (AMP)) those who would gossip and spread rumors. This applies to friends, family anyone who does such acts including ourselves. Yes, I know, we can not disassociate from ourselves but we can reform ourselves from our actions. Let me explain.
In today’s modern age of Social Media, this is becoming more and more common for “Christians” every day. How easy it is to see a Facebook post and share it, a tweet, and like it never checking to see if it is 100% accurate. Anytime we; like, share, repost, reblog or encourage such actions without ensuring the 100% legitimacy of the article, meme, etc. we are guilty of the sin of gossip, and spreading of rumors.
