What does the Bible say about fornication? The modern dictionary definition of fornication is voluntary sexual intercourse between persons not married to each other, which would include adultery.

In the Old Testament, all sexual sin was prohibited by the Mosaic Law and Jewish custom. However, the Hebrew word transcribed as “fornication” in the Old Testament was also in the meaning of idolatry. The word “fornication” is used in association with heathen idols because much of pagan “worship” involved sex in their rituals. Adultery, alternatively, invariably refers to the sexual sin of married people with someone other than their spouse.
