2. they . . . sent unto . . . house of God--The Jews of the country sent to the house of God or congregation at Jerusalem. The altar was long since reared (Ezr 3:3), though the temple was not completed till two years afterwards (Ezr 6:15). The priests' duty was to give decision on points of the law (De 17:9; Mt 2:4). Beth-el is here used instead of Beth-Jehovah, because the religious authorities, rather than the house itself (designated "Beth-Jehovah" in Zec 7:3), are intended. The old Beth-el had long ceased to be the seat of idol-worship, so that the name had lost its opprobrious meaning. "The house of the Lord" is used for the congregation of worshippers headed by their priests (Zec 3:7; Ho 8:1). MAURER makes the "house of God" nominative to "sent." HENDERSON makes "Beth-el" so.
      Sherezer--an Assyrian name meaning, "Prefect of the treasury."
      Regemmelech--meaning, "The king's official." These names perhaps intimate the semi-heathen character of the inquirers, which may also be implied in the name "Beth-el" (Hebrew for "house of God"), so notorious once for its calf-worship. They sent to Jehovah's house as their forefathers sent to old Beth-el, not in the spirit of true obedience.
      pray before the Lord--literally, "to entreat the face of," that is, to offer sacrifices, the accompaniment of prayers, to conciliate His favor (1Sa 13:12).
