Midrash su Salmi 21:4

Another interpretation (of Ps. 24:8 & 10): WHO IS THIS KING OF GLORY? Who is he? This is the king who distributes glory to those who fear him (according to vs. 10, cont.): THE LORD OF HOSTS, <HE IS THE KING OF GLORY>.⁴⁵Tanh., Exod. 2:8; M. Pss. 21:2; below, Numb. 2:24; 3:15; and the other parallels listed there. In what way? In the case of a king of flesh and blood, no one sits on his throne;⁴⁶See Sanh. 2:5, which affirms this royal prerogative along with the two which follow. yet the Holy One had Solomon sit on his throne. It is so stated (in I Chron. 29:23): THEN SOLOMON SAT UPON THE THRONE OF THE LORD. In the case of a king of flesh and blood, no one rides upon his horse; yet the Holy One had Elijah ride on his horse. Now what is the horse of the Holy One? Whirlwind and storm, as stated (in Nahum 1:3): THE LORD IS IN THE WHIRLWIND, AND THE STORM IS HIS ROAD.⁴⁷Tanh., Exod. 2:8; Exod. R. 8:1; M. Pss. 21:2; and below, Numb. 2:34, all cite II Kings 2:11 here to show when Elijah rode the whirlwind of the Holy One. In the case of a king of flesh and blood, no one uses his scepter; yet Moses used the scepter of the Holy One. It is so stated (in Exod. 4:20): AND MOSES TOOK THE ROD OF GOD IN HIS HAND. In the case of a king of flesh and blood, no one puts on his crown; yet the Holy One has given crowns to the Messianic King. It is so stated (in Ps. 21:4): YOU HAVE SET ON HIS HEAD A CROWN OF FINE GOLD. In the case of a king of flesh and blood, no one puts on his robes; yet Israel has put on the Holy One's robes, <i.e.,> strength. It is so stated (in Is. 51:9): AWAKE, AWAKE, PUT ON STRENGTH, O ARM OF THE LORD; and he has given it to Israel, as stated (in Ps. 29:11): THE LORD WILL GRANT STRENGTH TO HIS PEOPLE. In the case of a king of flesh and blood, no one calls <anyone else> by his title, as <for example> Caesar, Augustus, <or> King;⁴⁸Gk.: Basileus. and, if a certain person calls anyone by one of them, he will not live. Do you yourself know a person who calls his friend Augusta so-and-so? But the Holy One said to Moses: See, I have made you like me to Pharaoh. I am called God; and in that name I created the world, as stated (in Gen. 1:1): IN THE BEGINNING GOD CREATED THE HEAVENS AND THE EARTH. And here I have made you like me, a god to Pharaoh. Thus it is stated (in Exod. 7:1) SEE, I HAVE SET YOU AS A GOD TO PHARAOH. Ergo (in Ps. 24:8 & 10): WHO IS THIS KING OF GLORY? The one who distributes glory to those who fear him.

...Why was the Holy Blessed One called the King of glory?  Because He distributes glory to those who fear Him.  How so?  A king of flesh and blood, no one rides on his horse, and no one sits on his throne. But the Holy Blessed One had Solomon sit upon His throne, as it says "Solomon sat on the throne of the Lord as king" (I Chronicles 29:23).  And [the Holy Blessed One] had Elijah ride on His horse.  What is the horse of the Holy Blessed One? Whirlwind and storm! As it says "God travels in whirlwind and storm and clouds are the dust on His feet" (Nachum 1:3) and it is written "Elijah ascended in the storm to heaven" (II Kings 2:11).  A king of flesh and blood, no one uses his scepter, but the Holy Blessed One, gave His scepter to Moses, as it says "Moses took the staff of God in his hand" (Exodus 4:20).  A king of flesh and blood, no one wears his crown, but the Holy Blessed One will have the Messiah wear His crown.  What is the crown of the Holy Blessed One? Finest gold, as it says "His head is finest gold, His locks are curled, black as a raven." (Song of Songs 5:11),  and it is written, "You have set upon his head a crown of fine gold" (Psalms 21:4). A king of flesh and blood, no one wears his clothing, but Israel wears the clothing of the Holy Blessed One.  What is the clothing of the Holy Blessed One? Strength, as it says "the LORD is robed, girded with strength" (Psalms 93:1), and He gave it to Israel as it says "God gives strength to Israel, God blesses His people with peace" (Psalms 29:11)... 

No one may use the scepter of a human king, but the Holy One, blessed be He, handed His scepter to Moses, as it is said: And Moses took the scepter of the Lord in his hand (Exod. 4:20). No one would dare don the crown of a human king, but in the future the Holy One, blessed be He, will place His crown upon the head of King Messiah. What is the crown of the Holy One, blessed be He, like? The crown of the Holy One, blessed be He, is of the finest gold, as it is said: His head is of the most fine gold (Song 5:11), and it is also written about Him elsewhere: Thou settest a crown of fine gold on his head (Isa. 21:4).
