Sirach 11:29–34
29Don’t bring every man into your house, for many are the tricks of a deceitful man.
30Like a decoy partridge in a cage, so is the heart of a proud man. Like a spy, he looks for your weakness.
31For he lies in wait to turn things that are good into evil, and assigns blame in things that are praiseworthy.
32From a spark of fire, a heap of many coals is kindled, and a sinful man lies in wait to shed blood.
33Take heed of an evil-doer, for he plans wicked things, lest perhaps he ruin your reputation forever.
34Receive a stranger into your house, and he will distract you with arguments and estrange you from your own family.
