(Ibid. 6) "And he said to Moses: I, your father-in-law, Yithro, am coming to you; and your wife and her two sons with her": R. Yehoshua says: He wrote this to him in a letter. R. Elazar Hamodai says: He sent it by messenger, writing therein: Do it for me; and if not for me, then come out for your wife. And if not, do it for her sons. R. Eliezer says: The Holy One Blessed be He said to Moses: I am the one who spoke and brought the world into being. I am the one who draws near and not the one who distances, viz. (Jeremiah 23:23) "Am I only a G d from near, says the L rd, and not a G d from far?" I am the one who drew Yithro near and did not distance him. You, too, when a man comes to you to be converted, he does so only for the sake of Heaven. You, too, draw him near and do not distance him. From here we learn that a man should distance with the left hand and draw near with the right, and not do as Elisha did to Gechazi, rejecting him with both hands.
The Sages taught: Always have the left hand drive sinners away and the right draw them near, so that the sinner will not totally despair of atonement. This is unlike Elisha, who pushed away Gehazi with his two hands and caused him to lose his share in the World-to-Come, and unlike Yehoshua ben Peraḥya, who pushed away Jesus the Nazarene with his two hands. ...Now Naaman, the general of the army of Aram, was a leper. A certain young Jewish woman who had been taken captive from Eretz Yisrael said to him: If you go to Elisha, he will heal you. When Naaman came to him, Elisha said to him: Go immerse in the Jordan. Naaman said to him: Are you mocking me by suggesting that this will cure me? Those companions who were with Naaman said to him: What is the difference to you? Go, try it. Naaman went and immersed in the Jordan and was healed. Naaman came and brought to Elisha all those items that he had taken with him from Aram, and Elisha did not agree to receive them from him. Gehazi took leave from before Elisha and went and took from Naaman what he took, and he deposited them. When Gehazi came, Elisha saw the leprosy that had grown on Gehazi’s head. ...Then Elisha said to Gehazi: “The leprosy of Naaman shall cleave to you and to your seed forever. And he went out of his presence a leper as white as snow” (II Kings 5:27). With regard to the verse: “And there were four men afflicted with leprosy at the entrance of the gate” (II Kings 7:3), Rabbi Yoḥanan says: These were Gehazi and his three sons, as he and his descendants were cursed. § What is the incident involving Yehoshua ben Peraḥya? The Gemara relates: When King Yannai was killing the Sages, Yehoshua ben Peraḥya and Jesus, his student, went to Alexandria of Egypt. When there was peace between King Yannai and the Sages, Shimon ben Shataḥ sent a message to Yehoshua ben Peraḥya: From me, Jerusalem, the holy city, to you, Alexandria of Egypt: My sister, my husband is located among you and I sit desolate. The head of the Sages of Israel is out of the country and Jerusalem requires his return. Yehoshua ben Peraḥya understood the message, arose, came, and happened to arrive at a certain inn on the way to Jerusalem. They treated him with great honor. Yehoshua ben Peraḥya said: How beautiful is this inn. Jesus, his student, said to him: But my teacher, the eyes of the innkeeper’s wife are narrow [terutot]. Yehoshua ben Peraḥya said to him: Wicked one! Do you involve yourself with regard to that matter, the appearance of a married woman? He produced four hundred shofarot and ostracized him. Jesus came before Yehoshua ben Peraḥya several times and said to him: Accept our, i.e., my, repentance. Yehoshua ben Peraḥya took no notice of him. One day Yehoshua ben Peraḥya was reciting Shema and Jesus came before him with the same request. Yehoshua ben Peraḥya intended to accept his request, and signaled him with his hand to wait until he completed his prayer. Jesus did not understand the signal and thought: He is driving me away. He went and stood a brick upright to serve as an idol and he bowed to it. Yehoshua ben Peraḥya then said to Jesus: Repent. Jesus said to him: This is the tradition that I received from you: Whoever sins and causes the masses to sin is not given the opportunity to repent. And the Master says: Jesus performed sorcery, incited Jews to engage in idolatry, and led Israel astray. Had Yehoshua ben Peraḥya not caused him to despair of atonement, he would not have taken the path of evil.
