A worker may not do his own work at night
and hire himself out during the day,
or thresh with his cow in the evening
and hire her out for the day;
nor may he starve himself,
giving away his own food to his children,
because he will be depriving his employer
of the benefit of his work,
since he will be physically and mentally weakened
and therefore be unable to do the work
for his employer with strength.
