Can one go upon hot coals, and his feet not be burned?
– Proverbs 6:28
[T]his verse echoes the previous verse, giving an emphasis to the lesson. Hot coals are the burning coals or embers of a fire. Walking or going upon the coals indicates a continued action. Walking a path of hot coals will burn the feet. Both verses provide an inescapable conclusion, being burned. Fire is destructive and needs little to catch and burn (James 3:5). Fire can also quickly get out of control to where there is no putting it out. It is an apt description of the dangerous consequences of adultery.
