Sirach 28:23

23 Such as forsake the Lord shall fall into it; and it shall burn in them, and not be quenched; it shall be sent upon them as a lion, and devour them as a leopard.

Sirach 28:23 In-Context

21 The death thereof is an evil death, the grave were better than it.
22 It shall not have rule over them that fear God, neither shall they be burned with the flame thereof.
23 Such as forsake the Lord shall fall into it; and it shall burn in them, and not be quenched; it shall be sent upon them as a lion, and devour them as a leopard.
24 Look that thou hedge thy possession about with thorns, and bind up thy silver and gold,
25 And weigh thy words in a balance, and make a door and bar for thy mouth.
