As charity comprises the two commandments to which the Lord related the whole Law and the prophets... [Matt 22:39] so the Ten Commandments were themselves given on two tablets. Three were written on one tablet, and seven on the other. (Augustine, Sermon 33.2.2)
Tablet 1: Love of God
1. Idolatry
2. Blasphemy
3. Sabbath rest
Tablet 2: Love of Neighbor
4. Honor your father and mother
5. Murder
6. Adultery
7. Theft
8. False Witness
9. Coveting a Neighbor’s Wife
10. Coveting a Neighbor’ Property
