Midrash su Salmi 73:17

(Fol.39b) R. Simon b. Lakish said: "Where do we find a hint in the Torah that it is a duty to visit a sick person? From the following passage (Num. 16, 29) If these men die the common death of all men, and he visited after the visitation of all men, then the Lord hath not sent me." How does he infer it from this? Said Raba, it means thus: "If these men die as old men die, that they will be sick upon their beds and people will visit them. What will then people say? 'The Lord has not sent these plagues to them.'" Raba lectured: "What is the meaning of the passage (Ib., ib.) But if the Lord create a new thing [why repeated twice the verb create?] This means: If Gehenna had been created for them, it is all right; but if not, then the Lord should create it now for them." Is this so? Have we not been taught in a Baraitha that seven things preceded the creation of the world? They are the Torah, Repentance, Paradise, Gehenna, the Throne of the Divine Majesty, the Temple, the name of Messiah. That the Torah [was created before creation we infer] from the following passage (Pr. 8, 22) The Lord made me the beginning of His way. As for Repentance, it is written (Pr. 90, 2) Before yet the mountains were brought forth, etc., and after it is written Thou turnest man to contrition and sayest, 'Return ye children of men! As for Paradise, it is written (Gen. 2, 3) And the Lord God planted a garden in Eden (Mikedem) to the eastward. As for Gehenna, it is written (Is. 30, 33) For already of old is Topeth made ready. As for the Throne of the Divine Majesty and the Temple, it is written (Jer. 17, 12) A Throne of glory, exalted from the beginning of time, is the place of our Sanctuary. And as for the name of Messiah, it' is written (Ps. 72, 17) In the presence of the sun, his name shall flourish. Hence we see from the foregoing that Gehenna was created before creation.] We must therefore say that Moses said thus: "If the opening was created here, good and well; but if not, then let the Lord create it right here." But it is written (Ecc. 1, 9) There is nothing new under the sun. We must therefore explain it that Moses said: "If the opening is not around here, then let it be moved over there."

Samuel of Yarchina was the physician of Rabbi. When Rabbi had sore eyes, he said to him: "I shall inject some medicine into them." Rabbi said: "I cannot endure it." "I will smear some salve over it." But Rabbi answered him: "I cannot endure it." He then poured some medicine into a tube, placed it under his head while he was in bed, and he was cured. Rabbi essayed to invest Samuel with the title of Rabbi, but never had the opportunity, and Samuel said to him: "Let the master not be so sorry, for I have seen the book which was submitted to Adam the first, and in there it is written: Samuel of Yarchina (Fol. 86) will be named a sage, but not a Rabbi, and Rabbi will be cured through him. It is also written there: Rabbi and B. Nathan are the last of the Tannaic period (the Mishnah); R. Ashi and Rabina, the last of the Amorite period. The sign for this is (Ps. 73, 17) Until I enter the sanctuary of God and understand (Abina) what this future will be."
