'Itself' in the Bible

Every man's work will be made clear in that day, because it will be tested by fire; and the fire itself will make clear the quality of every man's work.

Love is never tired of waiting; love is kind; love has no envy; love has no high opinion of itself, love has no pride;

Love's ways are ever fair, it takes no thought for itself; it is not quickly made angry, it takes no account of evil;
