 The Torah obligates a man to not deprive his wife of food, clothing, or of sexual activity; if the husband does not provide the first wife with these things, she is to be divorced, without cost to her.The Talmud interprets this as a requirement for a man to provide food and clothing to, and have sex with, each of his wives, even if he only has one.As a polygynous society, the Israelites did not have any laws which imposed monogamy on men.
