The NKJV was commissioned in 1975 by Thomas Nelson Publishers. One-hundred-and-thirty respected Bible scholars, church leaders, and lay Christians worked for seven years with the goal of updating the vocabulary and grammar of the King James Version, while preserving the classic style of the of the 1611 version.

The task of updating the English of the KJV involved many changes in word order, grammar, vocabulary, and spelling. One of the most significant features of the NKJV was its removal of the second person pronouns "thou", "thee", "ye," "thy," and "thine." Verb forms were also modernized in the NKJV (for example, "speaks" rather than "speaketh").
