Incest

On more than one list of “Bible discrepancies” is the allegation that Bible writers erred in their teachings about incest. In Leviticus 18:6-30, 20:11-12, and Deuteronomy 27:20-23, one learns that sexual relations between close family members is sinful and punishable by death: “None of you shall approach anyone who is near of kin to him, to uncover his nakedness” (Leviticus 18:6). Other passages, however, indicate that God tolerated incest among His people, and even blessed those involved in such relationships. Abraham married Sarah, his half-sister (Genesis 20:12; cf. Genesis 17:15-16; 22:17), while Abraham’s son, Isaac, married Rebekah, his second cousin (Genesis 22:20-23; 24:4,15), and Jacob, Abraham’s grandson, married his first cousins, Rachel and Leah (Genesis 24:29; 29:15-30). Even Moses’ father, Amram, “took for himself Jachebed, his father’s sister, as wife” (Exodus 6:20, emp. added; cf. Leviticus 20:19). Critics claim that such passages are contradictory. Were Bible writers really inconsistent when they addressed the subject of incest?
