'Itself' in the Bible

But it is from Him that you are in Christ Jesus, who became to us wisdom from God [revealing His plan of salvation], and righteousness [making us acceptable to God], and sanctification [making us holy and setting us apart for God], and redemption [providing our ransom from the penalty for sin],

Do you not know that the saints (God’s people) will [one day] judge the world? If the world is to be judged by you, are you not competent to try trivial (insignificant, petty) cases?

Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,

Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;

For so it must be: this perishable nature must clothe itself with what is imperishable, and this mortality must clothe itself with immortality.
