Before the KJV ever saw the light of day, there were many other Bible translations.
There were the works of Wycliffe, Tyndale and Coverdale. There was the Matthew’s Bible of 1537, the Great Bible of 1539, the Geneva Bible of 1560 and the Bishops’ Bible of 1568.
Fact is, when the KJV came out, it was not readily accepted.
A Mr. Broughton, a Hebrew scholar of the day, wrote to King James that he “should rather be torn asunder by wild horses than allow such a version to be imposed on the church.”
The fact that a King (James) authorized a Bible translation does not make it the exclusive version.
Its just one translation ....and not the best one at that.
