The Trait of Arrogance

וְלֹא תָבִיא תוֹעֵבָה אֶל בֵּיתֶךָ 

Nor should you bring an abomination into your house [Eikev 7:26]

The verse teaches us, noted R' Levi Yitzchak of Berdichev, just how despicable the trait of arrogance truly is.  It is so abhorred that one is forbidden to even allow a haughty individual to enter his home.

We learn this from a verse in Mishlei: ''Every haughty heart is the abomination of Hashem'' [Mishlei 16:5]

We see, therefore, that a haughty individual is referred to as an ''abomination'', about which our verse explicitly states:  "And you must not bring an abomination into your home''.
