Sirach (Ecclesiasticus) 11:32-34 Good News Bible Catholic Edition (GNBDK)

32. A single spark can set a pile of coals ablaze, and a sinner is just waiting for a chance to use violence.

33. Watch out for such people and their evil plans; they will ruin you permanently.

34. If you bring a stranger home with you, it will only cause trouble, even between you and your own family.
