KJV Matt. 17:21, "Howbeit this kind goeth not out but by prayer and fasting."
NIV omits this verse from the text and places it in small print at the bottom of the page. The footnote says, "Some MSS add verse 21." (MSS is the abbreviation for manuscripts.).
KJV Matt. 18:11, "For the Son of man is come to save that which was lost."
NIV omits this verse from the text and places it in the footnote and says, "Some MSS add verse 11."
KJV Matt. 23:14, "Woe unto you, scribes and Pharisees, hypocrites for ye devour widows' houses, and for a pretense make long prayer: therefore ye shall receive the greater damnation."
NIV omits this verse in the same manner as above.
KJV Mark 7:16, "If any man have ears to hear, let him hear."
NIV omits this verse and says, "Some early MSS add verse 16."
KJV Mark 9:44, "Where their worm dieth not, and the fire is not quenched."
NIV omits this verse and does not even put it in the foot note.
KJV Mark 9:46, "Where their worm dieth not, and the fire is not quenched."
NIV omits this verse.
KJV Mark 11:26, "But if ye do not forgive, neither will you Father which is in heaven forgive your trespasses."
NIV omits this verse from the text.
KJV Mark 15:28 "And the scripture was fulfilled which saith, And he was numbered with the transgressors."
NIV omits this verse. Of course this is a blow at Christ since this refers to His fulfillment of Isa. 53:12.
KJV Luke 17:36, "Two men shall be in the field; the one shall be taken, and the other left."
NIV omits this verse that refers to His Second Coming.
KJV Luke 23:17, "(For of necessity he must release one unto them at the feast.)"
NIV omits this verse.
KJV John 5:3,4, "...waiting for the moving of the water. For an angel went down at a certain season into the pool, and troubled the water: whosoever then first after the troubling of the water stepped in was made whole of whatsoever disease he had."
NIV omits all of this which is part of verse 3 and all of verse 4.
KJV Acts 8:37, "And Philip said, If thou believest with all thine heart, thou mayest, And he answered and said, I believe that Jesus Christ is the Son of God."
NIV omits this verse, even though the eunuch's question is recorded in verse 36 and is translated as follows: "Look, here is water. Why shouldn't I be baptized?" Philip's answer in verse 37 is omitted, and he baptizes him with no confession of faith if we are to believe NIV. This is a very serious matter involving the salvation of the soul and we believe it is a serious error to tamper with God's Word in this way.
KJV Acts 15:34, "Not-withstanding it pleased Silas to abide there still,"
NIV omits this verse.
KJV Acts 24:7 "But the chief captain Lysias came upon us, and with great violence took him away out of our hands."
NIV omits verse 7 as well as part of verses 6 and 8.
KJV Acts 28:29, "And when he had said these words, the Jews departed and had great reasoning among themselves."
NIV omits this verse.
KJV Rom. 16:24, "The grace of our Lord Jesus Christ be with you all. Amen."
NIV omits this verse and places it in the foot note also.
KJV 1 Tim. 3:16, "And without controversy great is the mystery of godliness; God was manifest in the flesh..."
NIV 1 Tim. 3:16, "Beyond all question, the mystery of godliness is great; He appeared in a body..."
The KJV is very clear in showing that "God was manifest in the flesh", but NIV says "He appeared in a body..." The KJV shows that Jesus was God, while the NIV makes it unclear by substituting "He".
It's these and many more errors that pulled me away from the NIV. I once used the NIV and promoted this Bible as the one everyone should use. But after reading so many errors in this translation it was a wise choice to set this Bible down.
