There is grace for "errors" (like typo's, spelling, transpositions and things forgotten accidently). However, the modern versions make their changes deliberately. That's wrong.

So, if there is a KJV out there with "honest mistakes", it is still flawless and infallible. The fact God does anything perfect through an imperfect human is miraculous. God's Word is perfect and He preserves it perfect, and He oversees "cleansing" if they need to happen.

We all make tpyos.
