The modern method of celebrating becoming a
bar mitzvah did not exist in the time of the
Hebrew Bible,
Mishnah, or
Talmud. Early rabbinic sources specify 13 as the age at which a boy becomes a legal adult; however, the celebration of this occasion is not mentioned until the Middle Ages (from approximately 500
CE to 1500 CE; see
post-classical history). Some late
midrashic sources, and some medieval sources refer to a synagogue ceremony performed upon the boy's reaching age thirteen: •
Simon Tzemach Duran quotes a
Midrash interpreting the Hebrew word
zo ("this") in
Isaiah 43:21 ("These people have I formed for myself, they shall speak my praise") as referring by its
numerical value to those that have reached the age of 13. This seems to imply that, at the time of the composition of the Midrash the bar mitzvah publicly pronounced a blessing on the occasion of his entrance upon maturity. • The
Midrash Hashkem: "The heathen when he begets a son consecrates him to idolatrous practices; the
Israelite has his son circumcised and the rite of '
pidyon haben' performed; and as soon as he becomes of age he brings him into the
synagogue and
school in order that he may praise the name of God, reciting the
Barechu." •
Masseket Soferim (18:5) makes matters even more explicit: "In
Jerusalem they are accustomed to initiate their children to fast on the
Day of Atonement, a year or two before their maturity; and then, when the age has arrived, to bring the Bar Mitzvah before the
priest or elder for blessing, encouragement, and prayer, that he may be granted a portion in the
Law and in the doing of good works. Whosoever is of superiority in the town is expected to pray for him as he bows down to him to receive his blessing." •
Genesis Rabbah:
Age thirteen The Bible does not explicitly specify the age of 13. Passages in the books of
Exodus and
Numbers note the age of majority for army service as twenty.
Machzor Vitri notes that refers to
Levi as a "man", when a calculation from other verses suggests that Levi was aged 13 at the time. The age of thirteen is mentioned in the
Mishnah as the time one is obligated to observe the Torah's
commandments: "At five years old one should study the
Scriptures, at ten years for the Mishnah, at 13 for the commandments..." Elsewhere, the Mishnah lists the ages (13 for boys and 12 for girls) at which a vow is considered automatically valid; the
Talmud explains this as a result of the 13-year-old being a "man", as required in . (For one year before this age, the vows are conditionally valid, depending on whether the boy or girl has signs of physical maturity. • According to
Pirke Rabbi Eli'ezer 26,
Abraham rejected the total
idolatry of his father and became a worshiper of God when he was thirteen years old. The term "bar mitzvah", in reference to age, cannot be clearly traced earlier than the 14th century, the older
rabbinical term being "gadol" (adult) or "bar 'onshin" (one legally responsible for own misdoings). == Significance ==
