It was estimated that puberty, defined by the appearance of two pubic hairs, began in women early in the 13th year, and in men about the start of the 14th year, and for that reason maturity was regarded as beginning legally from the age of 12 years and one day in the case of females and 13 and one day in the case of males (Nid. 5:6; Nid. 52a). The rabbis reckoned religious responsibility to begin with the onset of puberty. From this period onward one was recognized as an adult, responsible for the observance of the precepts and the discharge of communal obligations. In the case of females, the rabbis delineated several distinct stages: ketannah ("minor"), from the age of three to the age of 12; the na'arah ("young woman"), for six months following the initial period; and the bogeret ("adult"), which begins at the expiration of these six months (Nid. 5:7). No such distinctions were made for the males who were simply ketannim ("minors") before 13 and gedolim ("adults") after their 13th birthday.

BB 121b) and only those above the age of 20 were liable for military service (Num. 1:3) or obligated to pay the half-shekel when the people were counted (Ex. 30:14).
