‘The age [category depends] upon the subject of the vow.’ How so? A young man who vowed the erech of an old man gives the erech of an old man, and an old man who vowed the erech of a young man gives the erech of a young man. ‘The arachin [depends] upon the subject of the erech.’ How so? A man who vowed the erech of a woman gives the erech of a woman, and a woman who vowed the erech of a man gives the erech of a man. ‘The erech [depends] upon the time of the erech.’ How so? [If] he vowed someone’s erech when he was less than five years of age, and he [then] became older than five; [or] less than twenty years of age and he [then] became older than twenty — he gives according to the time of the erech. The thirtieth day [is judged] as below this age; the fifth year and the twentieth year [are judged] as below this age; as it is said: And if from sixty years of age and up, if a male . . . (Lev. 27:7). We derive all of them from the sixtieth year. Just as the sixtieth year [is judged] as below this age, so too, the fifth year and the twentieth year are [judged] as below this age. Is this [indeed] so? If [Scripture] made the sixtieth year as below it, to be stringent, shall we [then] make the fifth year and the twentieth year as below it, to be lenient? To teach [us this,] it is said, years, years, for a gezeirah shavah. Just as [the] years mentioned in [regard to] the sixtieth year are [judged] as below it, so too [the] years mentioned in [regard to] the fifth year and the twentieth year [are judged] as below it, whether to be lenient or to be stringent. R’ Elazar says: Until they are over the years [by] one month and a day.
