Always look upon wicked men, under those names and
notions which the Scripture describes them, such as:
  lions for their fierceness,
  bears for their cruelty,
  dragons for their hideousness,
  dogs for their filthiness,
  wolves for their subtleness,
  scorpions,
  vipers,
  thorns,
  briars,
  thistles,
  brambles,
  stubble,
  dirt,
  chaff,
  dust,
  dross,
  smoke,
  scum.

You may know well enough what is within them, by the
apt names which the Holy Spirit has given them.
By looking upon them under those names and notions
that the Scripture sets them out by, may preserve the
soul from frequenting their company and delighting in
their society. Such monsters are wicked men--which
should render their company to all who have tasted of
the sweetness of divine love, a burden and not a delight.

"Blessed is the man who does not walk in the counsel
 of the wicked or stand in the way of sinners or sit in
 the seat of mockers." Psalm 1:1
