Galatians 6:4

But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another.

But let each man test his own work, and then he will take pride in himself and not in his neighbor.

But let each man prove his own work, and then shall he have his glorying in regard of himself alone, and not of his neighbor.

and his own work let each one prove, and then in regard to himself alone the glorying he shall have, and not in regard to the other,

Each one should test his own work. Then he will have reason to boast in himself alone, and not in someone else.
