Many modern bible translations are published with copyright claims. However published in the work is not only permission but a command to make a copy. This can be found in.
And it shall be, when he sitteth upon the throne of his kingdom, that he shall write him a copy of this law in a book out of that which is before the priests the Levites:
You might argue that this only applies to Kings. However Revelation 5:10 makes us all kings:
And hast made us unto our God kings and priests: and we shall reign on the earth.
It seems to me that if the translators wanted to copyright their translations they would have to leave Deuteronomy 17:18 out. However they all include it and it appears at least on face value to superseded their copyright notice.
Is this a valid legal argument? Has this has ever been tested in a court of law? And if so what was the outcome?
