The Ten Commandments, also known as the Decalogue, are a set of biblical laws relating to ethics and worship, which play a fundamental role in Judaism and Christianity. They include instructions to worship only God and to keep the sabbath, and prohibitions against idolatry, blasphemy, murder, theft, deception and adultery. Different groups follow slightly different traditions for interpreting and numbering them.
The Ten Commandments appear twice in the Hebrew Bible, in the books of Exodus and Deuteronomy. According to the story in Exodus, God inscribed them on two stone tablets, which he gave to Moses on Mount Sinai. Modern scholarship has found likely influences in Hittite and Mesopotamian laws and treaties, but is divided over exactly when the Ten Commandments were written and who wrote them.
