This phrase, which also appears in Acts 5:39, does not appear in the earliest and best resources—p74  א A B C (original hand) E Ψ. Latin, Syriac, and others—and does not appear until H L and P (all 9th century). As the original verse ended with a question, it is suspected that this phrase was taken from 5:39 to serve as an answer. Even before the KJV, it was omitted in the Wycliffe and Douay-Rheims versions. It was omitted from editions of the Greek New Testament at least as far back as 1729, in Daniel Mace's edition.
