Genesis 12:1-5

(1) יהוה said to Abram, “Go forth from your native land and from your father’s house to the land that I will show you.
(2) I will make of you a great nation,
And I will bless you;
I will make your name great,
And you shall be a blessing.
(3) I will bless those who bless you
And curse the one who curses you;
And all the families of the earth
Shall bless themselves by you.”(4) Abram went forth as יהוה had commanded him, and Lot went with him. Abram was seventy-five years old when he left Haran.(5) Abram took his wife Sarai and his brother’s son Lot, and all the wealth that they had amassed, and the persons that they had acquired in Haran; and they set out for the land of Canaan. When they arrived in the land of Canaan,

As y'all know, the preposition ל has many meanings and functions. In this comment Rashi is articulating his understanding of its meaning here.

רש"י על בראשית י״ב:א׳:א׳

(א)לך לך.לַהֲנָאָתְךָ וּלְטוֹבָתְךָ, שָׁם אֶעֶשְׂךָ לְגוֹי גָדוֹל, כָּאן אִי אַתָּה זוֹכֶה לְבָנִים, וְעוֹד שֶׁאוֹדִיעַ טִבְעֲךָ בָּעוֹלָם:

Rashi on Genesis 12:1:1

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)

רש"י על בראשית י״ב:ב׳:א׳

(א)ואעשך לגוי גדול. לְפִי שֶׁהַדֶּרֶךְ גּוֹרֶמֶת לִשְׁלֹשָׁה דְבָרִים, מְמַעֶטֶת פְּרִיָּה וּרְבִיָּה וּמְמַעֶטֶת אֶת הַמָּמוֹן וּמְמַעֶטֶת אֶת הַשֵּׁם, לְכָךְ הֻזְקַק לִשְׁלֹשָׁה בְּרָכוֹת הַלָּלוּ, שֶׁהִבְטִיחוֹ עַל הַבָּנִים וְעַל הַמָּמוֹן וְעַל הַשֵּׁם:

Rashi on Genesis 12:2:1

ואעשך לגוי גדול AND I WILL MAKE OF THEE A GREAT NATION —Since travelling is the cause of three things—it decreases (breaks up) family life, it reduces one’s wealth and lessens one’s renown, he therefore needed these three blessings: that God should promise him children, wealth and a great name (Genesis Rabbah 39:11).

Rashi begins the following comment with the question he is answering. This type of comment explains what a sentence (or word or phrase), that is seemingly redundant, adds to the reader's understanding.

רש"י על בראשית י״ב:ב׳:ד׳

(ד)מארצך. וַהֲלֹא כְבָר יָצָא מִשָּׁם עִם אָבִיו וּבָא עַד חָרָן? אֶלָּא כָּךְ אָמַר לוֹ הִתְרַחֵק עוֹד מִשָּׁם וְצֵא מִבֵּית אָבִיךָ:

Rashi on Genesis 12:2:4

מארצך FROM THY LAND — But had he not already departed from there together with his father and had reached as far as Haran (Genesis 11:31)? But thus God in effect said to him: Go still further away — leave now thy father’s house also.

רש"י על בראשית י״ב:ג׳:א׳

(א)ונברכו בך. יֵשׁ אַגָּדוֹת רַבּוֹת, וְזֶהוּ פְשׁוּטוֹ, אָדָם אוֹמֵר לִבְנוֹ תְּהֵא כְּאַבְרָהָם, וְכֵן כָּל וְנִבְרְכוּ בְךָ שֶׁבַּמִּקְרָא, וְזֶה מוֹכִיחַ בְּךָ יְבָרֵךְ יִשְׂרָאֵל לֵאמֹר יְשִׂמְךָ אֱלֹהִים כְּאֶפְרַיִם וְכִמְנַשֶּׁה (בר' מ"ח):

Rashi on Genesis 12:3:1

ונברכו בך AND IN THEE SHALL BE BLESSED — There are many Agadoth concerning this but the plain sense of the text is as follows: A man says to his son, “Mayest thou become as Abraham”. This, too, is the meaning wherever the phrase ונברכו בך “And in thee shall be blessed” occurs in Scripture, and the following example proves this: (Genesis 48:20) בך יברך “By thee shall Israel bless their children saying, “May God make thee as Ephraim and Manasseh”.

The verb לעשות has many different meanings but is still somewhat strange here. Rashi is offering a few possibilities.

רש"י על בראשית י״ב:ה׳:א׳

אשר עשו בחרן. שֶׁהִכְנִיסָן תַּחַת כַּנְפֵי הַשְּׁכִינָה; אַבְרָהָם מְגַיֵּר אֶת הָאֲנָשִׁים וְשָׂרָה מְגַיֶּרֶת הַנָּשִׁים, וּמַעֲלֶה עֲלֵיהֶם הַכָּתוּב כְּאִלּוּ עֲשָׂאוּם; וּפְשׁוּטוֹ שֶׁל מִקְרָא עֲבָדִים וּשְׁפָחוֹת שֶׁקָּנוּ לָהֶם, כְּמוֹ עָשָׂה אֵת כָּל הַכָּבֹד הַזֶּה (שם ל"א), וְיִשְׂרָאֵל עֹשֶׂה חָיִל (במדבר כד יח), לְשׁוֹן קוֹנֶה וְכוֹנֵס:

Rashi on Genesis 12:5:1

אשר עשו בחרן [THE SOULS] THAT THEY HAD GOTTEN (literally, made) IN HARAN — The souls which he had brought beneath the sheltering wings of the Shechinah. Abraham converted the men and Sarah converted the women and Scripture accounts it unto them as if they had made them (Genesis Rabbah 39:14). However, the real sense of the text is that it refers to the men-servants and to the maidservants whom they had acquired for themselves. The word “עשה” is used here as (in Genesis 31:1), “he has acquired (עשה) all this wealth”, and (Numbers 24:8), “And Israel acquires (עושה) wealth” — an expression for acquiring and amassing.
