the sanctuary, and for Judah
To make atonement in a typical way, having respect to the sacrifice of the Messiah, for the sins of the king, his family and court, among whom idolatry had prevailed in the times of his father; and for the cleansing of the temple, which had been polluted by the idolatries of Ahaz; and for the expiation of the whole land; seven of each sort are ordered, though only one goat was required for a sin offering by the law, because of the multitude of transgressions that had been committed, and because of the length of time in which sacrifices had been neglected: and he commanded the priests the sons of Aaron to offer them on the
altar of the Lord:
the altar of burnt offerings, whose business it was to do it.
