Incoherent babbling.
I was wrong on one of those two.
Both of them.
That changes nothing about the fact that your God did not think it necessary to address slavery in his top 10 rules, but decided to glorify himself in 30% of them.
Nothing about the ten commandments makes them the 'top ten'. The gospel is not a song hit chart.
God does not need to glorify Himself, and none of the Ten commands talk about God glorifying Himself.
1. You shall have no other gods before me.
This is not self glorifying. It is a directive. Don't waste your time with false idols (which has been a problem, and still is). Don't worship a statue (graven image). This includes images of Mary, images of Baal, images the Pope, images of Santa Claus. This includes not worshiping the weather, climate, Gaia, etc.
2. Make no idols.
A similar directive. Do not worship anything for God, which gave you life and light.
3. Do not take the Lord's name in vain.
This is similar to the 1st command again, not self glorifying. Worshiping God does not mean using Him as a curse, or to take his gospel lightly.
Let's look at a few others:
4. Keep the Sabbath holy.
This is for the benefit of Man. A day of rest, just as God took. Also a good day to acknowledge what God has done for the world.
5. Honor thy father and mother.
A directive for children. After all, they brought you into this world, and taught you many things about it. The came before you and you can benefit from this experience they have.
Abuse of children is also covered elsewhere in the Bible.
6. Thou shalt not kill.
This means other people. This is referring to the act of murder, not self defense or protecting the public from harm.
7. Thou shalt not commit adultry.
Pretty simple. Don't cheat on your wife, don't spend your time in whorehouses, don't treat sex lightly.
8. Thou shalt not steal.
Pretty simple as well. Don't swipe what isn't yours.
9. Thou shalt not bear false witness against thy neighbor.
Pretty simple. This not just a council for a courtroom. It is about libel and slander as well. In general gossip is an evil thing.
10. Thou shalt not covet.
Pretty simple as well. Keeping up with the Jones's is an expensive habit, easily lands you into a debt you can't afford, and can lead to stealing and abusing others.
This is not the entirety of the gospel (not even near it!), but it's a good start.
