The WH NU reading has the earliest support among the manuscripts. The extra verse was added by scribes, borrowing it directly from 4:23 (see also 4:9) to provide an ending to an otherwise very short pericope, 7:14–15. This addition was included in TR and made popular by KJV, NKJV, NASB, NJB, and HCSB also include this extra verse.
