17 The breathing out of true words gives knowledge of righteousness; but a false witness gives out deceit.

18 There are some whose uncontrolled talk is like the wounds of a sword, but the tongue of the wise makes one well again.

Whisperings and evil surmises, like a sword, separate those that have been dear to each other. The tongue of the wise is health, making all whole.
