Pidyon HaBen

פדיון הבן‎

The pidyon haben, (פדיון הבן‎) or redemption of the first born son, is a mitzvah in Judaism whereby a Jewish firstborn son is "redeemed" (bought back by the family) by use of silver coins. The redemption is attained by giving five silver coins to a Kohen (a patrilineal descendant of the priestly family of Aaron).
