That would include the KJV! Many legitimate reasons have been given but KJ onlyists largely ignore them.
The King James Bible causes us to slow down so as to meditate on it and seek God’s help with it. Psalms 119:148 says, “My eyes anticipate the night watches, That I may meditate on Your word.” Psalms 119:169 Says, “O LORD: give me understanding according to thy word.” So while the KJB critics may say that the King James Bible is too hard and archaic to understand, they need to realize that God desires us to meditate on His Word and that we are to ask for help in understanding it. Nowhere in Scripture does it teach that God’s Word should be as easy to understand as if one was reading a children’s book. We should engage with the Word thoughtfully and prayerfully, allowing its wisdom and guidance to permeate our lives (See also Joshua 1:8, and Psalms 25:5).
