An emission of semen: this is not an infectious disease as in verses 2-12. What is involved here is an involuntary act (as opposed to verse 18) in which the sperm of any male is emitted. Languages typically have very different ways of referring to such matters. The translation should be meaningful but should avoid shocking the reader or hearer unnecessarily.

His whole body: the context seems to indicate that the word body is probably to be taken in its more literal sense here rather than as a euphemism for the sexual organ. However, it is true that the expression used for bathing here differs somewhat from “bathe in water” used earlier in this chapter. This leads some commentators to believe that this is a euphemistic expression. The word translated body here is the same as the one rendered “flesh” in verse 7.
