Rabbi Yosi Mizrachi claims that Jesus cannot be the Messiah, because when he was on the cross he begged God to save him, but God didn’t save him and he wasn’t able to save himself. In the New Testament, Matthew describes what happened: “And about the ninth hour Jesus cried out with a loud voice, saying, ‘Eli, Eli, lema sabachthani?’ that is, ‘My God, my God, why have you forsaken me?’” (Mt. 27:46)
Rabbi Yosi Mizrachi believes that Jesus begged God to save him, but that is not quite what Matthew described. Actually, Matthew gives the answer to Rabbi Mizrachi's claim when he says, "Jesus cried out with a loud voice"... Jesus was not addressing God, but was shouting so that the crowd could hear him. He shouted in Aramaic: “Eli, Eli, lema sabachthani?” which means: “My God, my God, why have you forsaken me?” These are the very words that King David wrote at the beginning of Psalm 22. Jesus addressed the crowd in their spoken language, in Aramaic, so that they would hear and understand. In other words, Jesus wasn't asking God for help, but he was deliberately quoting King David's words in Psalm 22.
