פירוש על קידושין 34:6

Why should the slave be bequeathed to the son but not to the brother or any other heir? The first answer is that there is a tie between the father and so that does not exist for other heirs. A father can designate a female Hebrew slave to marry his son. And if a son redeems a consecrated ancestral field owned by his father, then the field returns to his possession at the Jubilee.
