17The breathing out of true words gives knowledge of righteousness; but a false witness gives out deceit.
18There are some whose uncontrolled talk is like the wounds of a sword, but the tongue of the wise makes one well again.
19True lips are certain for ever, but a false tongue is only for a minute.
20Deceit is in the heart of those whose designs are evil, but for those purposing peace there is joy.
21No trouble will come to upright men, but sinners will be full of evil.
22False lips are hated by the Lord, but those whose acts are true are his delight.
23A sharp man keeps back his knowledge; but the heart of foolish men makes clear their foolish thoughts.
