Proverbios 4

For they sleep not, unless they can do mischief,—They rob themselves of their sleep, if they cannot cause someone to stumble,

Porque no duermen ellos, si no hicieren mal; y pierden su sueño, si no han hecho caer.

For they sleep not, except they have done mischief; and their sleep is taken away, unless they cause some to fall.

For they don’t sleep unless they do evil. Their sleep is taken away, unless they make someone fall.
