Leviticus is a most interesting and important book; a book containing a code of sacrificial, ceremonial, civil, and judicial laws, which, for the purity of their morality, the wisdom, justice, and beneficence of their enactments, and the simplicity, dignity, and impressive nature of their rites, are perfectly unrivalled, and altogether worthy of their Divine Author. All the rites and ceremonies of the Mosaic law are at once dignified and expressive. They point out the holiness of their Author, the sinfulness of man, the necessity of an atonement, and the state of moral excellence to which the grace and mercy of the Creator have destined to raise the human soul. They include, as well as point out, the gospel of the Son of God; from which they receive their consummation and perfection. The sacrifices and oblations were significant of the atonement of Christ; the requisite qualities of these sacrifices were emblematical of his immaculate character; and the prescribed mode in the form of these offerings, and the mystical rites ordained, were allusive institutions, calculated to enlighten the apprehensions of the Jews, and to prepare them for the reception of the Gospel. The institution of the high priesthood typified Jesus, the Great High Priest, called and prepared of God, who hath an unchangeable priesthood, and is able to save to the uttermost all that come unto God by him.
