| Gill's Exposition of the Entire Bible 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.
Keil and Delitzsch Biblical Commentary on the Old TestamentAfter the issue had ceased, she was to purify herself like the man with an issue, as described in Leviticus 15:13-15. - Obedience to these commands is urged in Leviticus 15:31 : "Cause that the children of Israel free themselves from their uncleanness, that they die not through their uncleanness, by defiling My dwelling in the midst of them." הזּיר, Hiphil, to cause that a person keeps aloof from anything, or loosens himself from it, from נזר, Niphal to separate one's self, signifies here deliverance from the state of uncleanness, purification from it. Continuance in it was followed by death, not merely in the particular instance in which an unclean man ventured to enter the sanctuary, but as a general fact, because uncleanness as irreconcilable with the calling of Israel to be a holy nation, in the midst of which Jehovah the Holy One had His dwelling-place (Leviticus 11:44), and continuance in uncleanness without the prescribed purification was a disregard of the holiness of Jehovah, and involved rebellion against Him and His ordinances of grace.
Geneva Study BibleBut 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.
Wesley's Notes 15:28 Seven days - From the stopping of her issue. And this was for trial, whether it was only a temporary obstruction, or a real cessation.
Matthew Henry's Concise Commentary15:1-33 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. |
