1) to cut around
 2) to circumcise
    2a) cut off one's prepuce (used of that well known rite by which
        not only the male children of the Israelites, on the eighth
        day after birth, but subsequently also "proselytes of
        righteousness" were consecrated to Jehovah and introduced into
        the number of his people)
    2b) to get one's self circumcised, present one's self to be
        circumcised, receive circumcision
    2c) since by the rite of circumcision a man was separated from the
        unclean world and dedicated to God, the word is transferred to
        denote the extinguishing of lusts and the removal of sins
