Midrash su Salmi 68:5

Our sages stated in the name of R. Eleazar the son of Pedat: The Holy One, blessed be He, likens Himself to the humblest of men in seven places in the Torah. It is written: For the Lord your God, He is God of Gods, and the Lord of Lords, the great God, the mighty and the awful (Deut. 10:17), and this is followed by the verse: He doth execute justice for the fatherless and widow, and loveth the stranger (ibid., v. 18). It says likewise: For though the Lord be high, yet regardeth He the lowly (Ps. 138:6), and also: Thus saith the High and Lofty One that inhabiteth eternity and whose name is holy: I dwell in the high and holy places, with him also that is of a contrite and humble spirit, to revive the spirit of the humble (Isa. 57:15). Similarly, Scripture says: Thus saith the Lord: The heaven is My throne, and the earth is My footstool (ibid. 66:1), and that is followed by: And on this man will I look, even on him that is poor and of a contrite spirit and trembleth at My word (ibid., v. 2). Elsewhere it is written: The Lord is King forever and ever. The nations are perished out of His land (Ps. 10:16), and that is followed by the verse: Lord, Thou hast heard the desire of the humble (ibid., v. 17). Scripture says: Sing unto God, sing praises to His Name. Extol Him that rideth upon the skies, whose name is the Lord; and exult ye before Him (ibid. 68:5), and after that is written: A father of the fatherless, the judge of the widows (ibid., v. 6). Likewise the verse Who made heaven and earth, the sea and all that in them is, who keepeth truth forever, who executeth justice for the oppressed (Ps. 146:6–7) is followed by: He upholdeth the fatherless, and the widow; and the way of the wicked He maketh crooked (ibid., v. 9).

Where it is stated (in Deut. 10:17): FOR THE LORD YOUR GOD IS GOD OF GODS…. See how great is < his > might and how great is < his > praise! Then what is written next (in vs. 18)? HE SECURES JUSTICE FOR THE ORPHAN AND WIDOW.
It is also written (in Ps. 138:6): FOR THOUGH THE LORD IS HIGH, HE HAS REGARD FOR THE HUMBLE….
It is also written (in Is. 57:15): [FOR] THUS SAYS THE HIGH AND EXALTED ONE, WHO INHABITS ETERNITY, WHOSE NAME IS HOLY: I INHABIT THE HIGH AND HOLY PLACE, WITH ONE ALSO THAT IS OF A CONTRITE AND HUMBLE SPIRIT.
It is also written (in Is. 66:1): THUS SAYS THE LORD: THE HEAVENS ARE MY THRONE AND THE EARTH IS MY FOOTSTOOL…. Then there is written (in vs. 2): ALL THESE MY HAND HAS MADE … YET UNTO THIS PERSON WILL I LOOK: UNTO ONE WHO IS POOR AND OF A CONTRITE SPIRIT.
And the rest are in the Book of Psalms (10:16): THE LORD IS KING FOR EVER AND EVER. Then there is written after that (in vs. 17): THE LONGING OF THE MEEK YOU HAVE HEARD, O LORD….
It is also written (in Ps. 68:5 [4]): SING TO GOD, PRAISE HIS NAME, BUILD A WAY FOR THE ONE WHO RIDES IN THE DESERT. What is written after it (in vs. 6 [5])? A FATHER OF ORPHANS AND AN ADVOCATE OF WIDOWS.
It is also written (in Ps. 146:1): HALLELUJAH. PRAISE THE LORD, O MY SOUL! And there is written in the same psalm (at vs. 6): WHO MADE HEAVEN AND EARTH. Then there is written (in vs. 7): WHO SECURES JUSTICE FOR THE OPPRESSED….

(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."
