Pride

Proverbs 16:18 (King James Version)

"¹⁸Pride goeth before destruction, and an haughty spirit before a fall."

So be humble, when you aid someone or do something for him/her, honor that person more than yourself. Have no pride in any good deed you've done, but be proud only of your good comrades.

Matthew 7:3-5 (King James Version)

"³And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?

⁴Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye?

⁵Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye."
