Rashi on Gen 12:1-7 & Gen 13:2-7, 14-17

(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) (2) 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).,ואברכך AND I WILL BLESS THEE —with wealth (Genesis Rabbah 39:11). ,והיה ברכה AND BE THOU A BLESSING — Blessings are entrusted to you; hitherto they were in My power — I blessed Adam and Noah — but from now on you shall bless whomsoever you wish (Genesis Rabbah 39:11) Another explanation is: AND I WILL MAKE THEE A GREAT NATION, this alludes to the fact that we say in our prayer “God of Abraham”; AND I WILL BLESS THEE — that we say, “God of Isaac”; AND I WILL MAKE THY NAME GREAT — that we say, “God of Jacob”. One might think that we should conclude the benediction in which these invocations are recited by mentioning again the names of all the patriarchs — the text therefore states “Be thou a blessing” meaning, with you (i.e. with your name only) shall they conclude the benediction and not with them (their names) (Pesachim 117b).,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.,אשר אראך WHICH I WILL SHOW THEE — He did not reveal to him at once which land it was in order that he should hold it in high esteem and in order to reward him for complying with each and every command. Similar is, (Genesis 22:2) “Take thy son — thine only son — whom thou lovest — even Isaac”; similar is (Genesis 22:2) “upon one of the mountains which I will tell thee of”; similar is, (Jonah 3:2) “And make unto it the proclamation that I shall tell thee of” (Genesis Rabbah 39:9). (3) 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”. (4) (5) 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. (6) ויעבר אברם בארץ AND ABRAHAM PASSED THROUGH THE LAND —he entered it.,עד מקום שכם UNTO THE PLACE OF SHECHEM — In order to pray on behalf of Jacob’s sons, anticipating the time when they would come to fight against Shechem.,אלון מורה THE PLAIN OF MOREH — This is Shechem (Sotah 32a). He showed him Mount Gerizim and Mount Ebal where Israel took upon themselves the oath to observe the Torah (cf. Deuteronomy 11:29 and Deuteronomy 111:30).,והכנעני אז בארץ AND THE CANAANITE WAS THEN IN THE LAND — They (the Canaanites) were gradually conquering the land of Israel from the descendants of Shem, for it had fallen to the share of Shem when Noah apportioned the earth amongst his sons, for it is said (Genesis 14:18) “And Melchizedek) king of Salem (Jerusalem)”. For this reason the Lord said to Abram (Genesis 12:7) “to thy seed will I give this land” — “I will in some future time return it to thy children who are descendants of Shem”. (7) ויבן שם מזבח AND HE BUILDED THERE AN ALTAR — in thanksgiving for the good tidings that he would have children, and for the good tidings that they would possess the land of Israel.

(2) כבד מאד VERY RICH (literally, very heavy) — heavily laden with burdens. (3) וילך למסעיו AND HE WENT ON HIS JOURNEYS — When he returned from Egypt to the land of Canaan he went and lodged in the same inns as he had stayed when he travelled to Egypt. This teaches you good manners: that one should not change his inn (Arachin 16b); (where the reason is given that one who does this constantly brings discredit on himself and on others). Another interpretation: on his return he paid the debts he had previously incurred (Genesis Rabbah 41:3). (In both these comments emphasis is placed on “his” — he went on his journeys i.e. the routes he had taken before.),מנגב FROM THE SOUTH — the land of Egypt lies to the South of the land of Canaan. (4) אשר עשה שם בראשונה [UNTO THE PLACE OF THE ALTAR] WHICH HE HAD MADE THERE AT THE FIRST and WHERE ABRAM HAD CALLED [UPON THE NAME OF THE LORD] (that is, ויקרא does not introduce a further action of Abram done at that time, but refers to a former one when he had called upon the Name of the Lord); but it may also be explained that it means that Abram now called there upon the Name of the Lord. (5) ההלך את אברם WHO WENT WITH ABRAM — What brought it about that he possessed all this? The fact that he was accompanying Abram (Genesis Rabbah 41:3; Pesikta Rabbati, שמיני). (6) ולא נשא אתם AND THE LAND WAS NOT ABLE TO BEAR THEM — It could not provide sufficient pasture for their cattle. The phrase is elliptical and a word must be supplied, for instance: the pasturage (מרעה) of the land was not able to bear them — for this reason the word נשא (masculine) is used (to agree in gender with מרעה; the suggestion is that נשא cannot have הארץ as subject since that noun is feminine). (7) ויהי ריב AND THERE WAS A QUARREL because Lot’s shepherds were wicked men and grazed their cattle in other people’s fields. Abram's shepherds rebuked them for this act of robbery, but they replied, “The land has been given to Abram, and since he has no son as heir, Lot will be his heir: consequently this is not robbery”. Scripture, however, states: “The Canaanite and the Perizzite abode then in the land”, so that Abram was not yet entitled to possession (Genesis Rabbah 41:5). (8) אנשים אחים BROTHERS — i. e. kinsmen. The Midrashic explanation is: that they resembled each other in their facial features (Genesis Rabbah 41:6). (9) אם השמאל ואימינה IF THOU WILT TAKE THE LEFT HAND, THAN I WILL GO TO THE RIGHT —Wherever you settle down I will not go far from you and I will stand by you as a shield and as a helper. Ultimately, indeed, he (Lot) was really in need of him, as it is said, (Genesis 14:14) “And Abram heard that his brother was taken captive etc.”,ואימינה I WILL GO TO THE RIGHT — The word means “I will direct myself towards the right”, just as ואשמאילה means “I will direct myself towards the left.” If you say that it should be punctuated וְאַיְמִינָה (the regular Hiphil form) I answer that in another place also we find this form, (2 Samuel 14:19) אם יש לְהֵמִין “none can turn to the right hand”, where the punctuation is not כי.

(14) אחרי הפרד לוט AFTER LOT WAS SEPARATED FROM HIM — So long as the wicked (Lot) was with him the word of God kept away from him (i. e. God had no communion with Abraham) (Midrash Tanchuma, Vayetzei 10). (15) (16) אשר אם יוכל איש SO THAT IF A MAN IS ABLE [TO COUNT] —just as it is impossible for the dust to be counted, so, too, your seed shall not be counted. (17) (18) ממרא MAMRE — the name of a man.
