The Apostles are not expected, are they, to quote and recall events "ver batem " with one another, are they ?
There is a reason why Paul apparently mis-quotes the scripture..because he is making a doctrinal point indicating change of dispensation.
But that no man is justified by the law in the sight of God, [it is] evident: for, The just shall live by faith.
Now look at the original reading.
Hab. 2: 4
Behold, his soul [which] is lifted up is not upright in him: but the just shall live by his faith.
There is a reason the Holy Spirit sometimes does not make an exact quote..in this case it is a change from ones "own" faith which justifies, to the faith of Christ. In the OT and in the tribulation, one could/ can lose the Holy Spirit and fall away..check the doctrinal context in Hebrews through revelation.
Ga. 2 : 20
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
Even Jesus did not directly quote the OT word for word.
Mt.4 : 4
But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
Now the original reading.
Deu. 8 : 3b
that he might make thee know that man doth not live by bread only, but by every [word] that proceedeth out of the mouth of the LORD doth man live.
This is not the fault of the translators nor the original text, but HOW the Holy Spirit intended it to be to preserve the cross references and the message that was conveyed.
Here is a reading that baffles many, but there is a REASON behind it.
Mt. 4: 17
From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.
Mk. 1: 14- 15
Now after that John was put in prison, Jesus came into Galilee, preaching the gospel of the kingdom of God,
15 And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
To say this or any other reading in the KJ is error or a mistake is dangerous..there are cross references to both "heaven" and "God" in referring to His kingdom.
The cross references and the culmination of His word makes explains all the terminology and makes the KJV without error when taken in the proper context DOCTRINALLY.
The KJV is the ONLY bible that does this .
2 Ti. 3:15-1715 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.
16 All scripture [is] given by inspiration of God, and [is] profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17 That the man of God may be perfect, throughly furnished unto all good works.
2 Ti. 2 : 15
15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
Study the KJV long enough, applying the CORRECT doctrine, and you will see it has NO error nor mistakes..the translators were meticulous and quadrupal checked by one another..there is NO mistakes.
