Though some pollutions here spoken of, were in their nature greater than others; yet it is well to observe, that all equally disqualified from approaching the sanctuary. And what did these things teach, but that our most holy things are only accepted in JESUS? Observe what is said, I the LORD do sanctify them. John 17:19.
Leviticus 22:4-9
4 What man soever of the seed of Aaron is a leper, or hath a running issue; he shall not eat of the holy things, until he be clean. And whoso toucheth any thing that is unclean by the dead, or a man whose seed goeth from him;
5 Or whosoever toucheth any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatsoever uncleanness he hath;
6 The soul which hath touched any such shall be unclean until even, and shall not eat of the holy things, unless he wash his flesh with water.
7 And when the sun is down, he shall be clean, and shall afterward eat of the holy things; because it is his food.
8 That which dieth of itself, or is torn with beasts, he shall not eat to defile himself therewith: I am the LORD.
9 They shall therefore keep mine ordinance, lest they bear sin for it, and die therefore, if they profane it: I the LORD do sanctify them.
