The absence of verse 21 from Matthew chapter 17 in some modern Bible translations is a matter of textual criticism, stemming from variations in the manuscript evidence. Early manuscripts of the New Testament differ in their inclusion of this specific verse, which mentions prayer and fasting as necessary for casting out a particularly difficult demon. The presence or absence of this verse is determined by which manuscripts a particular translation committee deems most reliable.
The significance lies in the debate surrounding the authority and reliability of different textual traditions. Some scholars argue that the verse was likely a later addition, influenced by similar passages in Mark’s Gospel, and therefore not part of the original text of Matthew. Others maintain its authenticity, pointing to its inclusion in a substantial number of manuscripts and its theological consistency with other teachings in the Gospels. Historically, the verse’s inclusion has been associated with emphasis on spiritual disciplines, particularly prayer and fasting, as essential for spiritual power.
