John 19:28

Μετὰ τοῦτο … Διψῶ. “After this, Jesus knowing that all things are now finished, that the scripture might be completely fulfilled, saith, I thirst.” Jesus did not feel thirsty and proclaim it with the intention of fulfilling scripture which would be a spurious fulfilment but in His complaint and the response to it, John sees a fulfilment of Psalms 69:22, εἰς τὴν δίψαν μου ἐπότισάν με ὄξος. Only when all else had been attended to (εἰδὼς κ. τ. λ.) was He free to attend to His own physical sensations.
