“the feast of the Passover.” Passover is one of three feasts—Passover, Pentecost, and Tabernacles—that required all adult Jewish males to go to Jerusalem (Exod. 23:14-17; 34:22, 23; Deut. 16:16). The imperfect tense of “went” shows they habitually went; compare Hendriksen’s translation: “His parents were in the habit of going to Jerusalem.” Since only males “of mature age” were required to go, that Mary also attended shows us Mary and Joseph were a devoted couple (See Hendriksen).
