Uncleanness

(as it is used here) means,

Moral impurity; sinfulness;
unlawful indulgence of lust, fornication or adultery;
lack of restraint
of the sexual
appetite.




Now the works of the flesh are manifest,
which are these;
Adultery, fornication, uncleanness, lasciviousness,
Idolatry, witchcraft, hatred, variance, emulations,
wrath, strife, seditions, heresies,
Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do
such things shall not inherit
the kingdom of God.

Galatians 5:19-21
