1 Thessalonians 5:14-15

14We [earnestly] urge you, believers, admonish those who are out of line [the undisciplined, the unruly, the disorderly], encourage the timid [who lack spiritual courage], help the [spiritually] weak, be very patient with everyone [always controlling your temper].

15See that no one repays another with evil for evil, but always seek that which is good for one another and for all people.
