4 MOSEBOG 18:16

Hine skal du lade udløse, når de er en Måned gamle eller derover, med en Vurderingssum af fem Sekel efter hellig Vægt, tyve Gera på en Sekel.

And those that are to be redeemed from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary, which is twenty gerahs.
