The words of the wicked lie in wait for blood,
but the speech of the upright rescues them.
There are going to be roughly a million verses about speech in Proverbs and I'm pretty happy about that because I tend to run my mouth. The thing that's interesting about this verse is that it doesn't say who the words are lying in wait for.
Did you notice that? It's easy to assume that it's other people. That the words are going to wound others, but then in the second part of the verse, the consequences of speech are assigned to the speaker, not someone else.
So maybe the first person the words of the wicked are lying in wait for is the person speaking them. Maybe the blood my wicked words want the most is my own. Certainly I've wounded people with my gossip, but I think the person that suffers the most when I speak wickedly is me. That's my blood. I do not escape unscathed when I speak wickedly.
Have you ever wounded yourself with your own words?
