'Themselves' in the Bible

to be sensible, pure, makers of a home [where God is honored], good-natured, being subject to their own husbands, so that the word of God will not be dishonored.

not stealing [things, regardless of value], but proving themselves trustworthy, so that in every respect they will adorn and do credit to the teaching of God our Savior.

This is a faithful and trustworthy saying; and concerning these things I want you to speak with great confidence, so that those who have believed God [that is, those who have trusted in, relied on, and accepted Christ Jesus as Savior,] will be careful to participate in doing good and honorable things. These things are excellent [in themselves] and profitable for the people.

Our people must learn to do good deeds to meet necessary demands [whatever the occasion may require], so that they will not be unproductive.
