Death of Jesus (Matthew 27:45-55). The sayings 'I thirst' and 'It is finished' are peculiar to St. John. The former explains, what the synoptics do not, why 'one of them ran and took a sponge, and filled it with vinegar,' etc. (Matthew 27:48; Mark 15:35).

28 After this, Jesus knowing that all things were now accomplished, that the scripture might be fulfilled, saith,I thirst.
29 Now there was set a vessel full of vinegar: and they filled a spunge with vinegar, and put it upon hyssop, and put it to his mouth.
30 When Jesus therefore had received the vinegar, he said, It is finished: and he bowed his head, and gave up the ghost.
