Found these rib-ticklers at the Merrie Theologian, http://www.theologynetwork.org/.
In the 1562 edition of the Geneva Bible, Matthew 5:9 read ‘Blessed are the placemakers: for they shall be called the children of God.’
A 1716 edition of the King James Bible has Jesus say ‘sin on more’ in John 5:14, rather than ‘sin no more’.
A 1795 edition had Jesus say in Mark 7:27 ‘Let the children first be killed’ instead of ‘Let the children first be filled’.
Probably the worst mistakes, however, were made in the 1631 and 1653 ‘Wicked Bibles’. In the 1653 edition, 1 Corinthians 6:9 read ‘the unrighteous shall inherit the kingdom of God’ and the 1631 edition had the seventh commandment as ‘Thou shalt commit adultery.’ The bibles were ordered to be burned, and the sloppy (one hopes it was just sloppiness) printer fined a then-hefty £300.
