The wicked is snared by the transgression of his lips: but the just shall come out of trouble.
The wicked is snared by the transgression of (his) lips. The wicked thought to injure others by his transgression of God's law with his lips-namely, by false witness, calumnis, and lies; but it is ordered by God's retributive justice that it is himself who is snared in ruin thereby.
But the just shall come out of trouble - by avoiding the "transgression of his lips;" or if he has been betrayed into it by his own infirmity, or shall have been for a time snared by the lips of the transgressor, he "shall come out of trouble" through the grace of God.
