Charles Ellicott Commentary Proverbs 12:13

"In the transgression of the lips is a snare to the evil man; But the righteous shall come out of trouble." — Proverbs 12:13 (ASV)

The wicked is cursed by the transgression of his lips— For his words, the product of his evil heart, while designed to injure others, often bring the offender himself into trouble (Psalms 7:16), and moreover, as being the true index of the inner life of the soul, "are being stored up as a witness against him at the day of judgment" (Matthew 12:37). The "just man," on the contrary, avoids all this "trouble."
