The mere cessation of the issue does not make him clean: he must wait seven days, etc., preparatory to his offering sacrifice.

And when he that hath an issue is cleansed of his issue,.... That is, it is ceased from him, as the Targum of Jonathan and Jarchi explain it; for otherwise, according to the ceremonial law, he was not yet cleansed, until he had done everything next prescribed; but when he perceived there was an entire stop put to his disorder:

then he shall number to himself seven days for his cleansing; by which time it would appear whether he was thoroughly rid of it or not; and these seven days, as Jarchi observes, must be seven pure days, quite free from pollution, and continued in a constant course, without interruption; for, as Gersom says, if he saw any impurity in anyone of these days it did not come into the account: nay, according to Maimonides (b), he must begin to number again from the day of the last appearance:

and wash his clothes, and bathe his flesh in running water; typical of the fountain opened in Christ to wash in for sin and uncleanness, even the fountain of his blood, which cleanses from all sin; and in which both the persons and garments of the saints are washed and made white:

and shall be clean; in a ceremonial sense; as all that are washed from their sins in the blood of Christ are clean in a spiritual and evangelical sense.

(b) Hilchot Mechosre Capharah, c. 3. sect. 1.

When he was cleansed, i.e., recovered from his issue, he was to wait seven days with regard to his purification, and then wash his clothes and bathe his body in fresh water, and be clean. On the eighth day he was to bring two turtle-doves or young pigeons, in order that the priest might prepare one as a sin-offering and the other as a burnt-offering, and make an atonement for him before the Lord for his issue.

And when he that hath an issue is {e} cleansed of his issue; then he shall number to himself seven days for his cleansing, and wash his clothes, and bathe his flesh in running water, and shall be clean.

(e) That is, be restored to his old state, and be healed of it.

15:13 When he is cleansed - When his issue hath wholly ceased.

13, 14. then he shall number to himself seven days for his cleansing-Like a leprous person he underwent a week's probation, to make sure he was completely healed. Then with the sacrifices prescribed, the priest made an atonement for him, that is, offered the oblations necessary for the removal of his ceremonial defilement, as well as the typical pardon of his sins.

15:1-33 Laws concerning ceremonial uncleanness. - We need not be curious in explaining these laws; but have reason to be thankful that we need fear no defilement, except that of sin, nor need ceremonial and burdensome purifications. These laws remind us that God sees all things, even those which escape the notice of men. The great gospel duties of faith and repentance are here signified, and the great gospel privileges of the application of Christ's blood to our souls for our justification, and his grace for our sanctification.
