Deuteronómio 23:18 Halajá: Mishneh Torah, Marriage, Mishneh Torah, Forbidden Intercourse, Mishneh Torah, Negative Mitzvot & Sefer HaChinukh

Before the giving of the Torah, a man would meet a woman at the market and, if both of them wanted to, he would give her her wages and have intercourse with her and thereafter be on his way. Such a woman is called a cult-prostitude. Since the giving of the Torah, the cult-prostitude has become forbidden, for it says "There shall be no cult-prostitude among the daughters of Israel". Therefore, if one has intercourse after the manner of prostitution, without a legal and legitimate marriage, he shall receive Torah lashes because he had had intercourse with a prostitute.

i.e. The illegitimate children of a Hebrew servant and Caanite maid-servant are not considered Jews. Because of this, his father's seed was wasted because it did not go toward the birth of another Jew. This is said in Deuteronomy 23:18, "No Israelite man or woman shall become a temple prostitute."

2. When a mamzer marries a Jewish women or a Jewish man marries a female mamzer, once they enter into relations after consecration, they are punished by lashes. If the man consecrates the woman, but does not enter into relations, he does not receive lashes. If they enter into relations without consecration, they do not receive lashes because of relations with a mamzer. For the only instance where relations that involve a negative prohibition incur the punishment of lashes without the woman being consecrated is relations between a High Priest and a widow, as will be explained. When a man remarries his divorcee after she married another person, the offspring are acceptable. For she is not considered an ervah.
