וַיֹּאמֶר ה' אֶל אַבְרָם לֶךְ לְךָ מֵאַרְצְךָ וגו' (בראשית יב, א), רַבִּי יִצְחָק פָּתַח (תהלים מה, יא): שִׁמְעִי בַת וּרְאִי וְהַטִּי אָזְנֵךְ וְשִׁכְחִי עַמֵּךְ וּבֵית אָבִיךְ, אָמַר רַבִּי יִצְחָק מָשָׁל לְאֶחָד שֶׁהָיָה עוֹבֵר מִמָּקוֹם לְמָקוֹם, וְרָאָה בִּירָה אַחַת דּוֹלֶקֶת, אָמַר תֹּאמַר שֶׁהַבִּירָה הַזּוֹ בְּלֹא מַנְהִיג, הֵצִיץ עָלָיו בַּעַל הַבִּירָה, אָמַר לוֹ אֲנִי הוּא בַּעַל הַבִּירָה. כָּךְ לְפִי שֶׁהָיָה אָבִינוּ אַבְרָהָם אוֹמֵר תֹּאמַר שֶׁהָעוֹלָם הַזֶּה בְּלֹא מַנְהִיג, הֵצִיץ עָלָיו הַקָּדוֹשׁ בָּרוּךְ הוּא וְאָמַר לוֹ אֲנִי הוּא בַּעַל הָעוֹלָם. (תהלים מה, יב): וְיִתְאָו הַמֶּלֶךְ יָפְיֵךְ כִּי הוּא אֲדֹנַיִךְ. וְיִתְאָו הַמֶּלֶךְ יָפְיֵךְ, לְיַפּוֹתֵךְ בָּעוֹלָם, (תהלים מה, יב): וְהִשְׁתַּחֲוִי לוֹ, הֱוֵי וַיֹּאמֶר ה' אֶל אַבְרָם.
"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...].Rabbi Yitzchak opened: "Listen, daughter, look, and incline your ear, and forget your people and your father's house."
