And ye shall give her unto Eleazar the priest
The son of Aaron; the Sagan of the priests, as the Targum of Jonathan calls him, the second or deputy priest; it was not to be given to Aaron, that he might not be defiled, though but for a small time, that so he might not be hindered in his office at all; but to Eleazar, to inure him to his office, and to confirm him in it:
that he may bring her forth without the camp;
without the camp of Israel; Jarchi says, without the three camps, as afterwards without Jerusalem; it used in later times to be burnt on the mount of Olives; it was brought forth as impure, and was a type of Christ, having the sins of his people on him, and who in conformity to this type suffered without the gates of Jerusalem, see ( Hebrews 13:11-13 ) ;
and [one] shall slay her before his face;
the Targum of Jonathan says, another priest; but it was not necessary that it should be slain by a priest, any man might do it. Jarchi says, a stranger slew, and Eleazar looked on; though it was not slain by him, yet it was slain before him, that it might look like a sacrifice, though not offered on the altar; and slaying of it denotes the putting of Christ to death, which was done in the presence, and with the approbation, of the priests and elders of the people.
