Левит 15:4

Every bed upon which he lay, and everything upon which he sat, was defiled in consequence; also every one who touched his bed (Lev 15:5), or sat upon it (Lev 15:6), or touched his flesh, i.e., his body (Lev 15:7), was unclean, and had to bathe himself and wash his clothes in consequence.

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.
