39 Most witnesses (𝔓45, 74 A* C D E Ψ 33 1739 𝔐 latt sy bo) here read “the Holy Spirit” (τὸ πνεῦμα τὸ ἅγιον, to pneuma to hagion), while a few key have simply τὸ πνεῦμα (א Ac B sa mae). Although it is possible that some scribes omitted τὸ ἅγιον because of its perceived superfluity (note vv. 15, 17, 19), it is far more likely that others added the adjective out of pious motives.
