Deuteronomy 23:17-18
Purity in Cultic Personnel
23:17 There must never be a sacred prostitute among the young women of Israel nor a sacred male prostitute among the young men of Israel.
23:18 You must never bring the pay of a female prostitute or the wage of a male prostitute into the temple of the Lord your God in fulfillment of any vow, for both of these are abhorrent to the Lord your God.
