[PeterAV]

According to a certain Graham Pockett, he asserts that Matthew 17:21 in the AV is an addition by a copyist.

Here is his quote and my comment.

Graham writes:
Matthew 17:21 Howbeit this kind goeth not out but by prayer and fasting.
Comments about this “omission”: [in the NIV]
Verse 21 in the KJV was most likely added by a copyist to qualify the explanation that Jesus gave as to why He could cast out the demon and the Apostles could not. Whereas Jesus simply said they needed faith, the copyist obviously didn't think that this was enough and added the comment that you needed prayer and fasting as well. Reading the text, in context, clearly shows that this verse was added later and was most unlikely to have been in the original. Verse 22 starts a new teaching so verse 21 was the final verse in what Jesus was saying about faith. Typically, added verses are placed at the end of a discourse, not in the middle of one.

Most likely added?
You see? This is the huge problem that there are so many variants.
Nobody knows anything.
They set a hypothesis forward as the world does.
This is called scientific. LOL.

Matthew 17:21 is not an addition
Is there any pure Holy Bible in your mind?
I trow not.
It is deleted by the heretics that pimped out the Alexandrian perversions is the real story about that one.
And good godly men get sucked into believing these unsaved heretics.
If you are against the AV here, then you are against a whole slough of other Bibles because they also have that in there.

Looks like the International Standard Bible committee does not agree with your assumption here.
Also the translator committee of the NASB do not agree with you either.
There also are the committees of men from the

It is omitted because of Satanic influences.
Imagine taking the very power out of the word of God exactly where it is needed. {Fasting and Prayer}
But this is exactly what the modern versions often do.
They pick on all of the best and favorite verses in Christendom and pervert it and cause doubt to arise.
For shame.
