I am the Lord, your God.Thou shall bring no false idols before me.Do not take the name of the Lord in vain.Remember the Sabbath and keep it holy.Honor thy father and thy mother.Thou shall not kill/murder†.Thou shall not commit adultery.Thou shall not steal††.Thou shall not bear false witness against your neighbor.Thou shall not covet‡ your neighbor's wife (or anything that belongs to your neighbor).

( those are all 10 commandments)
