Sirach 11:29-34

29 Don't bring just anyone into your house, because deceitful people set many ambushes.

30 The hearts of arrogant people are like decoy birds in a cage; and like spies they will observe your downfall.

31 They set up ambushes and turn good into bad; they place blame on praiseworthy actions.

32 From a fire's spark come many coals, and sinful people plot and connive to shed blood.

33 Beware of evildoers, for they plan evil things, and they might bring lasting disgrace upon you.

34 If you allow strangers to live with you, they will twist you around in confusion and make you a stranger to your own family.
