As a priest
Because his section
Was on duty.”
Ἐγένετο δὲ ἐν τῷ ἱερατεύειν αὐτὸν ἐν τῇ τάξει τῆς ἐφημερίας αὐτοῦ ἔναντι τοῦ Θεοῦ,
Having described Zechariah and his wife, Luke turned to the action around Zechariah. This happened (Ἐγένετο) as he was serving as the priest (δὲ ἐν τῷ ἱερατεύειν αὐτὸν) before God (ἔναντι τοῦ Θεοῦ). His section or division of Levite priests were on duty (ἐν τῇ τάξει τῆς ἐφημερίας αὐτοῦ). Apparently, his group of Abijah priests served for 2 weeks at the Temple each year. Not bad, instead of 2 weeks off for vacation, they served for only 2 weeks a year, since there were 24 groups of priests with various tasks.
