3 For we are the circumcision, the ones who worship by the Spirit of God, exult in Christ Jesus, and do not rely on human credentials

Darby

3 For *we* are the circumcision, who worship by [the] Spirit of God^D8707, and boast in Christ Jesus, and do not trust in flesh.

Darby Bible Notes

God - T.R. reads 'God in spirit.' The reading was in question as early as Ambrose and Augustine. Augustine reads both. Ambrose, till the Benedictine edition, was given as reading Theo(i), 'serving God the Spirit.' but they give Theou, 'serving the Spirit of God.' The diplomatic evidence is in favour of Theou, 'who worship by the Spirit of God.' but I do not feel assured of its correctness. {aleph} has Theou; but after all {aleph} is only an Alexandrian witness of the completest kind. But it is anything but a correct manuscript. In Revelation it is very incorrect indeed. D and P (in Tisch. M.S.I.) read Theo-(i), and so Am Syrr.

KJV

3 For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
