3. Mose 14:7

Shall let the living bird loose - The Jews teach that wild birds were employed on this occasion, no tame or domestic animal was used. Mr. Ainsworth piously conjectures that the living and dead birds were intended to represent the death and resurrection of Christ, by which an atonement was made to purify the soul from its spiritual leprosy. The bird let loose bears a near analogy to the scapegoat. See Leviticus 16.

THE RITES AND SACRIFICES IN CLEANSING OF THE LEPER. (Lev. 14:1-57) law of the leper in the day of his cleansing--Though quite convalescent, a leper was not allowed to return to society immediately and at his own will. The malignant character of his disease rendered the greatest precautions necessary to his re-admission among the people. One of the priests most skilled in the diagnostics of disease [GROTIUS], being deputed to attend such outcasts, the restored leper appeared before this official, and when after examination a certificate of health was given, the ceremonies here described were forthwith observed outside the camp.

And he shall sprinkle upon him that is to be cleansed from the leprosy seven times,.... With the hyssop fastened to the cedar stick, with the scarlet wool or thread bound about it, dipped into the blood and water in the earthen vessel; to which the psalmist alludes, Psa 51:7; the Egyptians had a great notion of "hyssop", as of a purifying nature, and therefore used to eat it with bread, to take off the strength of that (d): upon what part of the leper this sprinkling was made is not said; the Targum of Jonathan says, upon the house of his face, that is, upon the vail that was over his face: but in the Misnah (e) it is said to be on the back of his hand; and so Gersom, though some say it was on his forehead; and sprinkling was typical of Christ's blood of sprinkling, and of the application of it, and of sharing in all the blessings of it; and this was done seven times, to denote the thorough and perfect cleansing of him, and of every part, every faculty of the soul, and every member of the body, and that from all sin, and the frequent application of it: the last mentioned writer says, at every sprinkling there was a dipping, and that the sense is, that he should sprinkle and dip seven times, as Naaman the Syrian leper did in Jordan; but of the washing of the leper mention is afterwards made: and shall pronounce him clean; from his leprosy, and so fit for civil and religious conversation, to come into the camp or city, and into the tabernacle: and shall let the living bird loose into the open field; as a token of the freedom of the leper, and that he was at liberty to go where he pleased: the Misnic doctors say (f), when he came to let go the living bird, he did not turn its face neither to the sea, nor to the city, nor to the wilderness, as it is said, "but he shall let…

The former chapter directed the priests how to convict a leper of ceremonial uncleanness. No prescriptions are given for his cure; but, when God had cured him, the priests are in this chapter directed how to cleanse him. The remedy here is only adapted to the ceremonial part of his disease; but the authority Christ gave to his ministers was to cure the lepers, and so to cleanse them. We have here, I. The solemn declaration of the leper's being clean, with the significant ceremony attending it (Lev 14:1-9). II. The sacrifices which he was to offer to God eight days after (v. 10-32). III. The management of a house in which appeared signs of a leprosy (v. 33-53). And the conclusion and summary of this whole matter (Lev 14:54, etc.).

14:7 Just as the goat released to Azazel symbolized the removal of sin from the community on the Day of Atonement (16:10, 20-22), the release of the live bird symbolized the removal of the individual’s uncleanness.
