(21-22) And whosoever toucheth her bed.--The regulations in these three verses are the same as those laid down in Leviticus 15:4-6.

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.And whosoever toucheth her bed,.... The same thing that is said of a profluvious man, and so in Leviticus 15:22.
