35 Grk “all these things thus being dissolved.”
36 Or “thus.”
37 Most have a pronoun with the infinitive—either ὑμᾶς (humas, “you”; found in A C[*] P Ψ 048vid 33 1739 𝔐, as well as the corrector of 𝔓72 and second corrector of א), ἡμᾶς (hēmas, “we”; read by א* 630 2464 al), or ἑαυτούς (heautous, “[you your]selves/[we our]selves,” read by 1243). But the shorter reading (with no pronoun) has the support of 𝔓72*,74vid B . Though slim, the evidence for the omission is nevertheless the earliest. Further, the addition of some pronoun, especially the second person pronoun, seems to be a clarifying variant. It would be difficult to explain the pronoun’s absence in some witnesses if the pronoun were original. That three different pronouns have shown up in the is testimony for the omission. Thus, on external and internal grounds, the omission is preferred. For English style requirements, however, some pronoun has to be added. has ὑμᾶς in brackets, indicating doubt as to its authenticity. Or “you.”
38 Grk “in holy conduct and godliness.”
