John 19: 28-37, The Death of Jesus

Jesus has been crucified. "This disciple" has been told, by Jesus from the cross, to take are of the mother of Jesus.

John 19: 28-30, Death
Later, knowing that everything had now been finished, and so that Scripture would be fulfilled, Jesus said, “I am thirsty.” 
29 A jar of wine vinegar was there, so they soaked a sponge in it, put the sponge on a stalk of the hyssop plant, and lifted it to Jesus’ lips. 
30 When he had received the drink, Jesus said, “It is finished.” With that, he bowed his head and gave up his spirit.

The ending is quick and dramatic; Jesus drinks a little bit of wine vinegar, announces that all has been done and dies. John records this as a deliberate act of Jesus, bowing his head and "giving up" his spirit, with the knowledge that he has completed his task. In this light, the statement, "It is over" represents triumph, not despair.

To provide Jesus with the wine vinegar, the people at the foot of the cross have to design a makeshift tool to get the moisture to him, wet sponge places on a stalk, held up high to reach his lips.

John 19: 31-37, Pierced
Now it was the day of Preparation, and the next day was to be a special Sabbath. Because the Jewish leaders did not want the bodies left on the crosses during the Sabbath, they asked Pilate to have the legs broken and the bodies taken down. 
32 The soldiers therefore came and broke the legs of the first man who had been crucified with Jesus, and then those of the other. 
33 But when they came to Jesus and found that he was already dead, they did not break his legs. 
34 Instead, one of the soldiers pierced Jesus’ side with a spear, bringing a sudden flow of blood and water. 
35 The man who saw it has given testimony, and his testimony is true. He knows that he tells the truth, and he testifies so that you also may believe. 
36 These things happened so that the scripture would be fulfilled: “Not one of his bones will be broken,”
37 and, as another scripture says, “They will look on the one they have pierced.”

Breaking the legs apparently hastened death because it made it difficult for the condemned man to push up and breathe. It also was a traumatic injury more likely to help bring on shock.

The quote in verse 36, "Not one of his bones shall be broken" reflects instructions about sacrificing the passover lamb (see Exodus 12:46 and Numbers 9:12) and is a phrase which also appears in Psalm 34:20. The second quote, verse 37, is from Zechariah 12:10.
