A.T. Robertson Commentary 2 Corinthians 11:27

"[in] labor and travail, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness." — 2 Corinthians 11:27 (ASV)

In labour and travail (κοπω κα μοχθω). Both old words for severe work, combined here as in 1 Thessalonians 2:9; 2 Thessalonians 3:8, "by toil and moil" (Plummer). The rest of the list is like the items in 2 Corinthians 6:4f..

In cold (εν ψυχε). Old word from ψυχω, to cool by blowing. See Ac 28:2. See the picture of the aged Paul later in the Roman dungeon (2 Timothy 4:9–18).
