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 he that sitteth on any thing whereon he sat that hath the issue,.... Shall be unclean, even though he does not touch it. Jarchi says, though there should be, as he adds, ten things or vessels one upon another, they all defile because of sitting, and so by lying:

shall wash his clothes, and bathe himself in water, and be unclean until the even; as in the preceding case. See Gill on Leviticus 15:5.
