The earliest manuscripts omit verse 24. It is not included in the Revised Standard Version, the New English Bible, An American Translation*, the Jerusalem Bible, and Moffatt. The New American Bible likewise omits this benediction, even though it has a verse 24 (the latter part of verse 23 in other translations).
