1. THE law requires, that out of the public expenses a lamb of the first year be killed every day, at the beginning and at the ending of the day; but on the seventh day, which is called the Sabbath, they kill two, and sacrifice them in the same manner. At the new moon, they both perform the daily sacrifices, and slay two bulls, with seven lambs of the first year, and a kid of the goats also, for the expiation of sins; that is, if they have sinned through ignorance.
