Thus, when Jesus' disciples went out among the people of Israel, testifying to Jesus, the people asked, "If your master is the Messiah, then where is the Elijah who is to come first?" So, Jesus disciples asked him, 'then why do the scribes say that first Elijah must come?' He replied, 'Elijah does come, and he is to restore all things; but I tell you that Elijah has already come, and they did not know him, but did to him whatever they pleased.' Then they understood that he was speaking to them of. John the Baptist." (Matt. 17:10-13).
