Gálatas 6

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

Así que cada uno examine su obra, y entonces tendrá gloria sólo respecto de sí mismo, y no en otro.

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.
