Kehillah in Thessalonika I 4:4-6

Orthodox Jewish Bible

⁴ That each one of you [as Kadoshim] have da’as of how to control your own k’li (vessel) in kedushah and kavod,

⁵ Not in the passion of ta’avah (evil desire, lust) like Goyim who do not have da’as of Hashem;

⁶ That no man commit peysha and take advantage of one of his Achim b’Moshiach in this [sexual] matter, because Hashem is the Nokem (Avenger) concerning all these things, just as also we told you before and warned you.
