John 17:17 “Sanctify them through thy truth: thy word is truth.”
Luke 11:28 “But he said, Yea rather, blessed are they that hear the word of God, and keep it.”
Not all Bible versions are the same and the version we choose is critical for sound doctrine. When studying the Scriptures is always good to compare the version we are reading with other good translation, that will give us more understanding on some words, or you can also use a bible dictionary.
The King James Bible is one of the best translations in the English language. Other Bibles translated from the Textus Receptus or Received Text (Majority Text) are also good but there are just a few bibles left today. Example: ‘The Interlinear Bible’ by Jay P. Green Sr. ; George Ricker Berry, Interlinear Greek-English New Testament, World Publishing, 1997, 1999 ; the ‘New King James’ Bible & the ‘Modern English Translation’.
What it’s important to look for is that the bible version we use is translated from the Received Text (Textus Receptus or Majority Text). Most modern translations like New International Version, The Living Bible, New Revised Standard, etc. have many parts translated from a corrupted manuscript or minority text, that comes from Alexandria Egypt and are not reliable translations, you will see some examples below. Also the Greek Interlinear by Wescott & Hort is corrupted, they used the minority text manuscripts and most new modern translation used this Wescott & Hort interlinear to translate their versions (this corrupted interlinear is used also by the Jehova’s Witnesses because attacks the Divinity of Jesus Christ). A quick test we can do : Any version of the Bible which omits Acts 8:37, and/or the word “through his blood” in Col. 1:14 evidently has for its foundation a corrupted manuscript.

Some bible verses that talk about the importance of keeping the Word of God pure:
