Левит 15:20

The Uncleanness of Secretions. - These include (1) a running issue from a man (Lev 15:2-15); (2) involuntary emission of seed (Lev 15:16, Lev 15:17), and the emission of seed in sexual intercourse (Lev 15:18); (3) the monthly period of a woman (Lev 15:19-24); (4) a diseased issue of blood from a woman (Lev 15:25-30). They consist, therefore, of two diseased and two natural secretions from the organs of generation.

In this chapter we have laws concerning other ceremonial uncleannesses contracted either by bodily disease like that of the leper, or some natural incidents, and this either, I. In men (v. 1-18). Or, II. In women (Lev 15:19-33). We need not be at all curious in explaining these antiquated laws, it is enough if we observe the general intention; but we have need to be very cautious lest sin take occasion by the commandment to become more exceedingly sinful; and exceedingly sinful it is when lust is kindled by sparks of fire from God's altar. The case is bad with the soul when it is putrefied by that which should purify it.
