I don't know if anyone's tried to read Greek... it's a horrible language with funny letters. If we in the 21st century have difficulty with it, I am not surprised that the Greeks did all those years ago.
I suspect that the answer is quite simple: whatever is the Greek for
"
Genesis 5:25 And Mathusala lived an hundred and sixty and seven years, and begot Lamech.
probably actually means
"And Mathusala lived for
somewhere about an hundred and sixty and seven years, and begot Lamech."
It is not at all unreasonable that God's word was garbled by some primitive scribe with a chisel if that scribe were Greek.
On the other hand, those Holy Men, inspired of God, who wrote the dictated Word of God (KJV1611) spoke original American and therefore no mistakes were made.
