At noon, darkness fell across the whole land until three o’clock. Then at three o’clock Jesus called out with a loud voice, “Eloi, Eloi, lema sabachthani?” which means “My God, my God, why have you abandoned me?”
Some of the bystanders misunderstood and thought he was calling for the prophet Elijah. One of them ran and filled a sponge with sour wine, holding it up to him on a reed stick so he could drink. “Wait!” he said. “Let’s see whether Elijah comes to take him down!”
Then Jesus uttered another loud cry and breathed his last. And the curtain in the sanctuary of the Temple was torn in two, from top to bottom.
When the Roman officer who stood facing him saw how he had died, he exclaimed, “This man truly was the Son of God!”
