Oh and whoever mentioned the ten commandments being a basis of our laws, do you realize that all of the moral ideals (not the ones like "don't worship idols", rather "don't kill people") existed well prior to the existence of the ten commandments in the form of Hammurabi's code, I would hardly call it basing the laws on the 10 commandments when none of the actual unique commandments are part of our law.
Edit: Oh and just for shites and jiggles, here are the real ten commandments, the ones written on the stone tablets:
1. I am making a covenant with you. Before all your people I will do wonders never before done in any nation in all the world. The people you live among will see how awesome is the work that I, the LORD, will do for you. Obey what I command you today.
2. I will drive out before you the Amorites, Canaanites, Hittites, Perizzites, Hivites and Jebusites.
3. Be careful not to make a treaty with those who live in the land where you are going, or they will be a snare among you.
4. Break down their altars, smash their sacred stones and cut down their Asherah poles [That is, symbols of the goddess Asherah].
5. Do not worship any other god, for the LORD, whose name is Jealous, is a jealous God.
6. Be careful not to make a treaty with those who live in the land; for when they prostitute themselves to their gods and sacrifice to them, they will invite you and you will eat their sacrifices.
7. And when you choose some of their daughters as wives for your sons and those daughters prostitute themselves to their gods, they will lead your sons to do the same.
8. Do not make cast idols.
9. Celebrate the Feast of Unleavened Bread. For seven days eat bread made without yeast, as I commanded you. Do this at the appointed time in the month of Abib, for in that month you came out of Egypt.
10. The first offspring of every womb belongs to me, including all the firstborn males of your livestock, whether from herd or flock.
11. Redeem the firstborn donkey with a lamb, but if you do not redeem it, break its neck.
12. Redeem all your firstborn sons. No one is to appear before me empty-handed.
13. Six days you shall labor, but on the seventh day you shall rest; even during the plowing season and harvest you must rest.
14. Celebrate the Feast of Weeks with the firstfruits of the wheat harvest, and the Feast of Ingathering at the turn of the year [That is, in the fall].
15. Three times a year all your men are to appear before the Sovereign LORD, the God of Israel.
16. I will drive out nations before you and enlarge your territory, and no one will covet your land when you go up three times each year to appear before the LORD your God.
17. Do not offer the blood of a sacrifice to me along with anything containing yeast, and do not let any of the sacrifice from the Passover Feast remain until morning.
18. Bring the best of the firstfruits of your soil to the house of the LORD your God.
19. Do not cook a young goat in its mother's milk.
As you can see they are quite different. Don't believe me? Grab a bible and turn to Exodus 34:27-28 which follows those statements.
