Paul writes about this in his letters. Some parts are hard. Some people who do not learn twist the words. They hurt themselves. They do this with the Bible too.
He writes this way in all his letters, speaking in them about such matters. Some parts of his letters are hard to understand, which ignorant and unstable people distort, as they do the rest of the Scriptures, to their own destruction.
KJV
As also in all [his] epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as [they do] also the other scriptures, unto their own destruction.
ASV
as also in all his epistles, speaking in them of these things; wherein are some things hard to be understood, which the ignorant and unstedfast wrest, as they do also the other scriptures, unto their own destruction.
Therefore, beloved, since you already know these things, be on your guard so that you will not be carried away by the error of the lawless and fall from your secure standing.
KJV
Ye therefore, beloved, seeing ye know [these things] before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
ASV
Ye therefore, beloved, knowing these things beforehand, beware lest, being carried away with the error of the wicked, ye fall from your own stedfastness.
