Uncleanness.
Had sin never entered, there had been no disease. Diseases are consequences of sin; their symptoms are therefore taken as emblems of it. So when our Lord miraculously "healed all manner of sickness, and all manner of disease," he evinced ability to remove all corresponding moral evil. The examples specified in the Law are typical or representative, and are such as have symptoms pronounced and visible.
I. THOSE WHO HAD ISSUES IN THE FLESH WERE UNCLEAN.
1. Out of a pure heart are the issues of life (see Proverbs 4:23).
2. Out of a foul heart are the issues of death.
3. The Law enjoined the separation of the unclean.
II. THEY RENDERED UNCLEAN WHATEVER THEY TOUCHED.
1. This signified the contagion of sin.
2. Ever, when cured they must be cleansed.
3. Observe the ceremonies of cleansing.
