Carrying out a wicked scheme is enjoyable to a fool, and so is wisdom for the one who has discernment.

The righteousness of the upright will save them, but by a scheme the treacherous will be taken captive.

A foolish scheme is sin,
and a mocker is detestable to people.

Like a [common] clay vessel covered with the silver dross [making it appear silver when it has no real value]
Are burning lips [murmuring manipulative words] and a wicked heart.
