Corruption in Bible?
The Revised Standard Version makes it even clearer: "How can you say, 'We are wise, and the law of the LORD is with us'? But, behold, the false pen of the scribes has made it into a lie. (From the RSV Bible, Jeremiah 8:8)"
In either translation, we clearly see that the Jews had so much corrupted the Bible with their man-made cultural laws, that they had turned the Bible into a lie!
See Also Deuteronomy 31:25-29 where Moses peace be upon him predicted the corruption/tampering of the Law (Bible) after his death.
The Book of Moses predicted that the Law (Bible) will get corrupted. The Book of Jeremiah which came approximately 826 years after did indeed confirm this corruption.
GOD prohibiting brothers from marrying their biological sisters after He initially allowed it for Abraham and Sarah:
"And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife. (Genesis 20:12)"
"Cursed be he that lieth with his sister, the daughter of his father, or the daughter of his mother. And all the people shall say, Amen. (Deuteronomy 27:22)"
It is important to know that in the same book of Genesis, GOD Almighty did Speak directly with Abraham. For instance:
1 The LORD had said to Abram, "Leave your country, your people and your father's household and go to the land I will show you.
2 "I will make you into a great nation and I will bless you; I will make your name great, and you will be a blessing.
3 I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you."
Yet, GOD never prohibited Abraham from marrying his own biological sister, Sarah!
So, Deuteronomy 27:22 is indeed an abrogation to the previous Law!
