"Thou shalt not commit adultery" (Biblical Hebrew: לֹא תִנְאָף, romanized: Lōʾ t̲inʾāp̲) is found in the Book of Exodus of the Hebrew Bible. It is considered the sixth commandment by Roman Catholic and Lutheran authorities, but the seventh by Jewish and most Protestant authorities. What constitutes adultery is not plainly defined in this passage of the Bible, and has been the subject of debate within Judaism and Christianity. The term fornication means illicit sex, prostitution, idolatry and lawlessness.

Thou shalt not murder. Thou shalt not commit adultery. Thou shalt not steal. Thou shalt not bear false witness against thy neighbour.

— Exodus 20:14
