(א) וַיֹּ֤אמֶר יְהוָה֙ אֶל־אַבְרָ֔ם לֶךְ־לְךָ֛ מֵאַרְצְךָ֥ וּמִמּֽוֹלַדְתְּךָ֖ וּמִבֵּ֣ית אָבִ֑יךָ אֶל־הָאָ֖רֶץ אֲשֶׁ֥ר אַרְאֶֽךָּ׃
(1) The LORD said to Abram, “Go forth from your native land and from your father’s house to the land that I will show you.
לך לך. לַהֲנָאָתְךָ וּלְטוֹבָתְךָ, שָׁם אֶעֶשְׂךָ לְגוֹי גָדוֹל, כָּאן אִי אַתָּה זוֹכֶה לְבָנִים, וְעוֹד שֶׁאוֹדִיעַ טִבְעֲךָ בָּעוֹלָם:
לך לך GET THEE OUT (literally, go for thyself) — for your own benefit, for your own good: there I will make of you a great nation whilst here you will not merit the privilege of having children (Rosh Hashanah 16b). Furthermore, I shall make known your character throughout the world (Midrash Tanchuma, Lech Lecha 3)
(י) וַיְהִ֥י רָעָ֖ב בָּאָ֑רֶץ וַיֵּ֨רֶד אַבְרָ֤ם מִצְרַ֙יְמָה֙ לָג֣וּר שָׁ֔ם כִּֽי־כָבֵ֥ד הָרָעָ֖ב בָּאָֽרֶץ׃ (יא) וַיְהִ֕י כַּאֲשֶׁ֥ר הִקְרִ֖יב לָב֣וֹא מִצְרָ֑יְמָה וַיֹּ֙אמֶר֙ אֶל־שָׂרַ֣י אִשְׁתּ֔וֹ הִנֵּה־נָ֣א יָדַ֔עְתִּי כִּ֛י אִשָּׁ֥ה יְפַת־מַרְאֶ֖ה אָֽתְּ׃ (יב) וְהָיָ֗ה כִּֽי־יִרְא֤וּ אֹתָךְ֙ הַמִּצְרִ֔ים וְאָמְר֖וּ אִשְׁתּ֣וֹ זֹ֑את וְהָרְג֥וּ אֹתִ֖י וְאֹתָ֥ךְ יְחַיּֽוּ׃ (יג) אִמְרִי־נָ֖א אֲחֹ֣תִי אָ֑תְּ לְמַ֙עַן֙ יִֽיטַב־לִ֣י בַעֲבוּרֵ֔ךְ וְחָיְתָ֥ה נַפְשִׁ֖י בִּגְלָלֵֽךְ׃
(10) There was a famine in the land, and Abram went down to Egypt to sojourn there, for the famine was severe in the land. (11) As he was about to enter Egypt, he said to his wife Sarai, “I know what a beautiful woman you are. (12) If the Egyptians see you, and think, ‘She is his wife,’ they will kill me and let you live. (13) Please say that you are my sister, that it may go well with me because of you, and that I may remain alive thanks to you.”
