I don't need a list because Paul the apostle said that there were no commandments between Adam and Moses in Romans 5. But if you want to prove Paul wrong, then go ahead. Post your list.
The law was not
written down until Moses at Mt. Sinai.
But obviously the principles of the 10 commandments were known since the days of Cain at least:
1) "Thou shalt have no other gods before me" - Gen 35:1-4
2) "Thou shalt not make unto thee any graven image..." - Gen 31:19, 34 & 35 and 35:2-4
3) "Thou shalt not take the name of the Lord thy God in vain" - Could not be broken before Moses learned God's name at the burning bush.
4) "Remember the Sabbath Day to keep it holy..." - Gen 2:1-3 is when it was first established. It was "made for man/mankind". The word for "man" in Hebrew is "Adam". It was also already known before the Israelites got to Mt. Sinai (Ex 16:4 & 22-30)
5) "Honor thy father and thy mother..." - Gen 9:22-25
6) "Thou shalt not kill/murder" - Gen 4:8-11, 23-24 and 9:5-6
7) "Thou shalt not commit adultery" - Gen chapt. 20; 38:24; 39:7-9
8) "Thou shalt not steal" - Gen 30:33; 31:19, 30&32; 44:8
9) "Thou shalt not bear false witness against thy neighbor" - Gen 39:7-20
10) "Thou shalt not covet..." - Had to be broken before the other commandments could be broken
These things were known sins (the "thou shalt not" ones anyway).
Rom 4:15 "...where no law is,
there is no transgression."
Rom 3:20 "...by the law
is the knowledge of sin"
I John 3:4 "Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law."
Did Cain commit a sin when he killed his brother? Why? Where was a law given to him that stated "Thou shalt not kill"?
Did Cain know it was wrong? Why did God punish him if he committed no sins?
Did Joseph know it would be a sin against his master (and against God) if he slept with Potiphar's wife?
Where's the commandment for that?
What about Sodom and Gomorrah? Why was the antediluvian world destroyed?
Where no law is there can be no transgression.
The law was not written down yet but obviously it was known at the time.
