Not for that we would be unclothed (Ephesians' hōi ou thelomen ekdusasthai). Rather, “For that (Ephesians' hōi) we do not wish to put off the clothing, but to put it on” (all' ependusasthai). The transposition of the negative ou weakens the sense. Paul does not wish to be a mere disembodied spirit without his spiritual garment.
That what is mortal may be swallowed up of life (hina katapothēi to thnēton hupo tēs zōēs). “Only what is mortal perishes; the personality, consisting of soul and body, survives,” (Plummer). See note on 2Co 1:22 for “the earnest of the spirit.”
