Galatians 6:2-5 King James Version (KJV)
2 Bear ye one another's burdens, and so fulfil the law of Christ.
3 For if a man think himself to be something, when he is nothing, he deceiveth himself.
4 But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another.
5 For every man shall bear his own burden.
