Jesus’ side was pierced
The crowd did not want the bodies left on the crosses during the Sabbath. They asked Pilate to break the legs of the three men so they would die faster. Since Jesus was already dead, the soldiers did not break his legs. One soldier took his spear and pierced Jesus’ side.
After Jesus died, he stopped talking, but he was not quiet. The things that happened to him were signs.
The blood that came from his side was the blood of the new covenant. The water was the water of baptism. "On that day a fountain shall be opened to cleanse them from sin and impurity," said Zechariah.
