Midras Yeremia 46:18: Ein Yaakov (Glick Edition), Mekhilta DeRabbi Yishmael & Bereshit Rabbah

(Ezek. 11, 16) Yet will I be to them as a minor sanctuary. R. Samuel b. Isaac said: "This refers to the houses of study that are in Babylon." R. Elazar said: "This refers to the house of our master who is in Babylon; i.e., Rab]." Raba lectured: What is the meaning of the passage (Ps. 90, 1) Lord, a place of refuge hast thou been unto us. That refers to the prayer- and learning-houses." Abayi said: "Formerly I used to learn at home, and pray at the house of Prayer; but since I heard what David said (Ps. 16, 6) Lord, I love the site of thy house, I began to study in the prayer-house also." In a Baraitha it was taught, R. Elazar ha-Kapar said: "The prayer - and learning - houses outside of the land of Israel will in the future be established in the land of Israel, as it is said (Jer. 46, 18) As Thabor is among the mountains, and as Carmel is by the sea, so shall He come, etc. Can this not be inferred through a fortiori conclusion? If Thabor and Carmel, at which only occasionally the Law was studied, are deemed within the land of Israel, how much more so will the prayer-houses and schools, at which the Law is studied, be established in the land of Israel?" Bar Kapara lectured: "What does this passage mean (Ps. 68, 17) Why watch ye enviously, ye many-peaked mountains? This means: A heavenly voice went forth and said to the mountains: 'Why should ye be jealous of Mount Sinai? Ye, all great mountains, are blemished in comparison with Sinai; for it is written Gabnunim in connection with mountains, and the same analogy of expression is used (Lev. 21, 20) A Giben (crook-backed) ." .From this," said Abaye, "we may infer that a man who is haughty is to be considered as blemished." (Fol. 31) R. Jochanan said: "Whenever you find in the Scripture a description of the greatness of the Holy One, praised be He! you find also a description of His modesty. This is written in the Pentateuch, repeated in the Prophets, and mentioned a third time in the Hagiographa. In the Pentateuch it is written (Deut. 10, 17) For the Lord your God is the God of gods, and the Lord of Lords; and immediately follows. Who executeth justice for the fatherless and the widow. It is repeated in the Prophets (Is. 57, 15) Thus hath said the High and Lofty One, who inhabiteth Eternity, whose name it Holy; and after this it is written: Yet also with the contrite and humble in spirit. The third time in Hagiographa (Ps. 68, 5) Extol him who rideth upon the heavens. The Everlasting is His name; and after this it is written: A father of the fatherless and the judge of the widows."

R. Nathan says: This is the retort to those heretics who would contend that there are two Deities. When the Holy One Blessed be He stood (at Mount Sinai) and said "I am the L–rd your G–d," who stood up and contended with Him? If you would say that this took place in concealment, is it not written (Ibid. 45:19) "Not in secret did I speak, etc." I did not reserve it (the Torah) for them alone. And thus is it written (Ibid.) "I, the L–rd, speak righteously; I tell what is true."

Variantly: "I am the L–rd your G–d": When the Holy One Blessed be He stood and said "I am the L–rd your G–d," the mountains shook and the hills quivered, and Tavor came from Be'er Elim and Carmel from Aspamia, as it is written (Jeremiah 46:18) "As I live, says the King — the L–rd of hosts is His name — that as Tavor among the mountains and as Carmel by the sea shall he come," each one saying "It is I who was called." But once they heard from His mouth "who took you out of the land of Egypt," each remained in its place, saying "He intends only those whom He took out of Egypt."... Variantly: "I am the L–rd your G–d": When the Holy One Blessed be He arose and proclaimed "I am the L–rd your G–d," the earth took ill, as it is written (Judges 5:4) "O L–rd, when You came forth from Seir, when You strode from the field of Edom, the earth shook; the heavens, too, dripped," and (Ibid. 5) "Mountains dripped before the L–rd," and (Psalms 29:4) "The voice of the L–rd in strength; the voice of the L–rd in glory!" … (Ibid. 9) "And in His sanctuary all proclaim "'Glory!'" Until their houses were suffused with the splendor of the Shechinah…
