Luke 2:41-42

Again Luke pointed out the godly characters of Mary and Joseph. Jewish males were to go to Jerusalem three times a year, at the feasts of Passover, Pentecost, and Tabernacles. In Jesus’ day, women usually attended with their husbands or fathers. [Note: Theological Dictionary of the New Testament, s.v. "pascha," by J. Jeremiah , 5:896-904.] Those who could not attend all three festivals tried to attend Passover at least. Customarily Jewish parents took their young sons with them for a year or two before the boy became a "son of the covenant" usually at age 13. [Note: Edersheim, 1:235-36.] Luke called Jesus a "boy" (Gr. pais, also used of servants) here rather than a "child" (Gr. paidion), the term he used of Jesus in Luke 2:40.

"Jewish boys became responsible for their actions at thirteen (m[ishnah]. Niddah 5.6; m[ishnah]. Megillah 4.6). At the age of twelve the instruction of boys became more intensive in preparation of the recognition of adulthood (m[ishnah]. ’Abot 5.21). The Bar Mitzvah of modern times, however, postdates the time of Jesus by five hundred years. . ." [Note: Bock, Luke, p. 99, n. 1. Cf. Fitzmyer, p. 440.]
