פּירוש אויף בראשית 38:21

הקדשה— means a woman who is devoted to, (מקדשת) and who is ever ready for illicit intercourse.

The cult prostitute [hakedeisha; הקדשה]. A woman available/prepared for sex, as in "purify yourselves [hitkadshu; התקדשו] for tomorrow" (Bamidbar 11:18).

הקדשה, the harlot; a woman who is always ready to have sexual relations with any male. The male equivalent of the term is found in Deuteronomy 23,18. where the Torah instructs the Jewish people not to tolerate this phenomenon, and in Kings I 14,24 where the presence of such male prostitutes is acknowledged with the words וגם קדש היה בארץ, a phenomenon which surfaced immediately after the death of King Solomon.
