Proverb for the Day 13:2 — It’s Up To Me!

From the fruit of their lips people enjoy good things, but the unfaithful have an appetite for violence

The two lines of this wise saying would seem to be unconnected at first glance. Yet, on closer inspection, I’ll suggest they actually offer an interesting comparison.
The first line appears to be about “people” in general, not a particular group based on any specific quality. “From the fruit of their lips” they “enjoy good things.”
Apparently this phrase suggests the general principle that anyone can benefit from their own words. We all have the opportunity to think and say that which will produce good things for our own lives, as well as for other people. 
It’s a good reminder for those of us who might be a bit pessimistic by nature or tend to be critical of others. 
In contrast, “the unfaithful” are those who are “deceitful,” even “betrayers.” They won’t be “enjoying good things!”
While those other folks bring good things into their own lives, the choices and actions of “the unfaithful” only bring “violence” to theirs. 
This verse simply offers another version of the famous Biblical phrase “we reap what we sow” (Galatians 6:7). Good thoughts and words bring good things into my life and I’ll also be in a place to have something meaningful to pass along to others, as well.
The alternative is to only expect unpleasantness in my own life — and have nothing of value for anyone else.
I think it’s pretty clear — whatever happens in this verse is up to me!
