Sirach 11:33-36 Catholic Public Domain Version (CPDV)

33. For it lies in ambush, and then turns good into evil, and it will place the blame on the elect.

34. From one spark, a great fire grows; and from one deceitful man, much blood flows. But a very sinful man lies in ambush for blood.

35. Pay close attention to yourself before a harmful man, for he fabricates evils. Otherwise, he may lead over you a whispered reproach unceasingly.

36. Receive a stranger to yourself, and he will overthrow you with a whirlwind, and he will alienate you from what is your very own.
