But it was Jacob’s polygamous marriages that particularly interested Joseph Smith, and he frequently referred to the new marriage principle as the blessing of Jacob. He was fond of pointing to the commandment in Exodus: “And if a man entice a maid that is not betrothed, and lie with her, he shall surely endow her to be his wife.” The sin of adultery lay not in the act itself but in the subsequent desertion. It was the abandonment of the humbled maid that led to the unspeakable evils of prostitution and infanticide.
