And he shall sprinkle upon him that is to be cleansed from the leprosy seven times. It is not certain whether the seven sprinklings were made upon the forehead of the person to be cleansed, or on the back of his hand.
The feathers of the bird and the bunch of hyssop would be specially instrumental in the seven sprinklings. And shall pronounce him clean. Having assured himself that he was healed (Leviticus 14:3), the priest now pronounces him to be clean, he looses as well as binds.
It had been his office to declare the man a leper, and thereby to shut him out from the people of the Lord (Leviticus 13:8, Leviticus 13:15, Leviticus 13:22, Leviticus 13:25, Leviticus 13:36, Leviticus 13:44, Leviticus 13:46).
Now he pronounces him to be no leper, and therefore, after some further ceremonies, readmits him (Leviticus 14:8, Leviticus 14:20, Leviticus 14:31). And shall let the living bird loose into the open field.
The symbolism of the two birds, which has been much misinterpreted, is essentially the same as that of the two goats on the day of atonement, though each ceremony has its distinctive features. The killing of the living bird was not a true sacrifice, as was the offering of the goat to Jehovah, but by its death it represented the state in which the leper had legally been, and to which he would have been physically reduced had not a remedy been found.
The deathly and unclean state of the leper having been symbolically transferred from the dead bird to the living bird by the latter's being sprinkled in the former's blood, the living bird stands in the position of the scapegoat, on whom the sins of the people were laid.
The bird is then let loose into the open field; literally, upon the face of the field; and it flies off, carrying with it the leper's uncleanness, and assuring him by every forward movement that it makes that the living death has passed from him, just as each step or' the scapegoat appeared to the Israelites to remove their sins from them.
A large number of commentators, on the other hand, consider the released bird to symbolize the health and freedom now given back to the leper, and they dwell on the rapid and uncontrolled movement of birds as being peculiarly suitable for representing this recovered liberty.
But this interpretation, to which there are many objections, appears to be altogether incompatible with the fact that the same ceremony is used in the cleansing of the leprous house, whereas the house could certainly not be represented as "recovered to unrestrained liberty" (Lunge).
The common patristic view, that the two birds represent the two natures of the one Great Sacrifice offered to redeem man from sin, seems to be out of place here.
