Verse 10, in many early biblical manuscripts (such as certain vg, cop, and arm), is rendered with the word "veil" () rather than the word "authority" (); the Revised Standard Version reflects this, displaying 1 Corinthians 11:10 as follows: "That is why a woman ought to have a veil on her head, because of the angels." Similarly, a scholarly footnote in the New American Bible notes that presence of the word "authority () may possibly be due to mistranslation of an Aramaic word for veil". This mistranslation may be due to "the fact that in Aramaic the roots of the word power and veil are spelled the same." Ronald Knox adds that certain Scripture scholars hold that "Paul is attempting, by means of this Greek word, to render a Hebrew word that signifies the veil traditionally worn by a married Jewish woman." The last-known living connection to the apostles, Irenaeus, penned verse 10 using the word "veil" () instead of "authority" () in Against Heresies, as did other Church Fathers in their writings, including Hippolytus, Origen, Chrysostom, Jerome, Epiphanius, Augustine, and Bede.
