'Selfishness' in the Bible

Do not let mercy and kindness and truth leave you [instead let these qualities define you];Bind them [securely] around your neck,Write them on the tablet of your heart.

For I am afraid that perhaps when I come I may find you not to be as I wish, and that you may find me not as you wish—that perhaps there may be strife, jealousy, angry tempers, disputes, slander, gossip, arrogance and disorder;

For you, my brothers, were called to freedom; only do not let your freedom become an opportunity for the sinful nature (worldliness, selfishness), but through love serve and seek the best for one another.

idolatry, sorcery, hostility, strife, jealousy, fits of anger, disputes, dissensions, factions [that promote heresies],

Do nothing from selfishness or empty conceit [through factional motives, or strife], but with [an attitude of] humility [being neither arrogant nor self-righteous], regard others as more important than yourselves.
