2 Corinthians 4:13

ἔχοντες δὲ τὸ αὐτὸ πν. κ. τ. λ.: but, sc., despite our bodily weakness and the “working of death in us” of 2 Corinthians 4:12, having the same spirit of faith, sc., as the Psalmist, according to that which is written, “I believed, and therefore I spoke,” we also believe, and therefore also we speak, sc., as the Psalmist did. The exact meaning of Psalms 115:1 in the original is hard to fix; but the context would not naturally suggest the beautiful thought here read into it. That faith must find expression, that it cannot be silent, is the Apostle's adaptation of the words. With τὸ πνεῦμα τῆς πίστεως cf. Romans 8:15; 1 Corinthians 4:21; Galatians 6:1; Ephesians 1:17; 2 Timothy 1:7, etc. Deissmann (Neue Bibelstudien, p. 78) illustrates the introductory formula of citation here employed by the legal formula κατὰ τὰ προγεγραμμένα which occurs in a Fayyûm papyrus of 52 A.D.
