¹ tn Or “worship.” The word here is λατρεύω (latreuw).

² tc The verb λατρεύω (latreuw; here the participial form, λατρεύοντες [latreuonte"]) either takes a dative direct object or no object at all, bearing virtually a technical nuance of “worshiping God” (see BDAG 587 s.v.). In this text, πνεύματι (pneumati) takes an instrumental force (“by the Spirit”) rather than functioning as object of λατρεύοντες. However, the word after πνεύματι is in question, no doubt because of the collocation with λατρεύοντες. Most witnesses, including some of the earliest and best representatives of the Alexandrian, Western, and Byzantine texts (א* A B C D² F G 0278^vid 33 1739 1881 Ï co Ambr), read θεοῦ (qeou; thus, “worship by the Spirit of God”). But several other important witnesses (א² D* P Ψ 075 365 1175 lat sy Chr) have the dative θεῷ (qew) here (“worship God by the Spirit”). Ì⁴⁶ is virtually alone in its omission of the divine name, probably due to an unintentional oversight. The dative θεῷ was most likely a scribal emendation intended to give the participle its proper object, and thus avoid confusion about the force of πνεύματι. Although the Church came to embrace the full deity of the Spirit, the NT does not seem to speak of worshiping the Spirit explicitly. The reading θεῷ thus appears to be a clarifying reading. On external and internal grounds, then, θεοῦ is the preferred reading.
