I know about the first two, but where can I find the third?
The irreguarlar state church changed the ten commandments by droping the first commandment making the second commandment the first.
And then spiting the 10th commandment into the 9th and 10th.
Out of the protestant reformation the then 1st commandent which was really the 2nd commandment called the first was spite making it into a 1st and 2nd commandment. Then restoring the 10th into one commandment.
The 1st commandment, Exodus 20:1, "
I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage."
God commands by His Name to Israel that He is to be their God.
The 2nd commandment, Exodus 20:2-6, "
Thou shalt have no other gods before me. . . ." This includeds not the using images to worship God.
The 3rd commandment, Exodus 20:7. Not to misuse God's Name. It being rendered as "the LORD" in our translations.
The 4th commandment, Exodus 20:8-11. The 7th day Sabbath which was given to Israel as a people.
The 5th commandment, Exodus 20:12.
The 6th commandment, Exodus 20:13.
The 7th commandment, Exodus 20:14.
The 8th commandment, Exodus 20:15.
The 9th commandment, Exodus 20:16.
The 10th commandment, Exodus 20:17.
