These two proverbs are very helpful for me. I like the bible teaching from Salem Bible Church about the verses (link below “Sparing Words”)
Now I know it is WISE to spare words, I just need to spare my words with greater and greater frequency.
27 The one who has knowledge uses words with restraint,
and whoever has understanding is even-tempered.
28 Even fools are thought wise if they keep silent,
and discerning if they hold their tongues.
