• Newari: “Someone who digs a pit may fall into it himself.
  The person who tears down a wall may be bitten by a snake.” (Source: Newari Back Translation)
• Hiligaynon: “If you (sing.) dig a pit, you (sing.) might fall. If you (sing.) break-through the hole of a stoned-wall, you (sing.) might be-bitten by a snake.” (Source: Hiligaynon Back Translation)
• English: “It is possible that those who dig pits
  will fall into one of those pits.
  It is possible that someone who tears down a wall
  will be bitten by a snake that is in that wall.” (Source: Translation for Translators)
