Galatians 6:4

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

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 examine his own work, and then he will have reason to boast in himself, and not in someone else.

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.
