Midrash su Salmi 45:12

Now the Lord said unto Abram: “Get thee out of thy country.” Scripture says elsewhere in reference to this verse; Hearken, O daughter, and consider, and incline thine ear; forget also thine own people and thy father’s house; so shall the king desire thy beauty; for he is thy lord; and do homage unto him (Ps. 45:11). Hearken, O daughter, and consider, and incline thine ear alludes to Abraham. Forget also thine own people, and thy father’s house refers to the idolaters, concerning whom it is said: Who say to a stock: “Thou art my father” (Jer. 2:27). And so shall the king desire thy beauty refers to the King of Kings, who desired to glorify your (Abraham’s) name in this world and in the world-to-come. For he is thy lord; and do homage unto him.

Another interpretation (of Gen. 12:1): GO. This text is related (to Ps. 45:11 [10]): HEAR, O DAUGHTER, TAKE NOTE, AND INCLINE YOUR EAR: FORGET YOUR PEOPLE AND YOUR FATHER'S HOUSE.⁸Tanh., Gen. 3:3; cf. Gen. R. 39:1. HEAR, O DAUGHTER, TAKE NOTE: This refers to Abraham. AND FORGET YOUR PEOPLE AND YOUR FATHER'S HOUSE: This refers to the idolaters, as stated (in Jer. 2:27): THEY SAY TO A TREE: YOU ARE MY FATHER. (Ps. 45:12 [11]) AND THE KING WILL DESIRE YOUR BEAUTY. This refers to the Supreme King of Kings, the Holy One, < who takes pleasure in > ⁹The reading follows the traditional Tanhuma. adorning you in the world. R. Abbin said: {(ibid.): BECAUSE HE IS YOUR LORD, BOW DOWN TO HIM.} Now what did Abraham resemble?¹⁰Cf. Gen. R. 39:2. A vial of persimmon¹¹Gk.: balsamon. when it has been set in a graveyard. Then no one would know what its aroma was. What did a certain one do? He took it and moved it from place to place, < so that > its aroma began to disperse abroad. Similarly Abraham was dwelling among those who served idols. The Holy One said to him: Why are you residing among the wicked? Go out from among them, and make your good works known abroad. Thus it is stated (in Gen. 12:1): GO.

"G-d said to Abram, 'Go forth from your land…'" (Genesis 12:1) Rabbi Yitzchak opened: "Listen, daughter, look, and incline your ear, and forget your people and your father's house." (Psalms 45:11) Rabbi Yitzchak said: this may be compared to a man who was traveling from place to place when he saw a castle aglow. He said, "Is it possible that this castle lacks a person to look after it?" The owner of the building looked at him and said to him, 'I am the master of the castle.'" What happened with Abraham our father was similar. He said, “Is it possible that this universe lacks a person to look after it?," the Holy Blessed One looked at him and said to him, 'I am the Master of the Universe.'" "And let the king be aroused by your beauty since he is your master" (Psalms 45:12) And let the king be aroused for your beauty in the universe. "And bow to him" (Psalms 45:12) Hence, G-d said to Abram, [go forth...].
