Midrash su Salmi 66:2

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).
