(28) But if she be cleansed.—That is, cured or healed of her infirmity. The expression “cleansed” is used both here and in Leviticus 15:13 for the disappearance of the complaint. From the time of its cessation she is to count seven days, during which no trace of the complaint must be observable, just as in the case of the less innocent disorder. (See Leviticus 15:13.)

After that she shall be clean.—That is, after having performed the rites of lustration.

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.This must refer to an unexpected occurrence.

Seven days from the stopping of her issue, as it is apparent. And this was for trial whether it was only a temporary obstruction, or a real cessation.

But if she be cleansed of her issue,.... The disease is healed, or a stop is put to it; there are no signs of it remaining:

then she shall number to herself seven days; from the time she observed it to cease:

and after that she shall be clean; having bathed herself according to the usual manner of unclean persons, for their cleansing; when she would be fit to be admitted to her husband, though not as yet into the tabernacle, until she had offered her offering next directed to.

But if she be cleansed of her issue, then she shall {k} number to herself seven days, and after that she shall be clean.

(k) After the time that she is recovered.
