32:13ל״ב:י״ג
1 א

היטב איטיב. הֵיטֵב בִּזְכוּתְךָ, אֵיטִיב בִּזְכוּת אֲבוֹתֶיךָ (בראשית רבה):

היטב איטיב I WILL SURELY DO [THEE] GOOD — The use of two words denoting “doing good” is intended to signify: היטב doing good to thee on account of your own merits, איטיב I will also do good to thee on account of your father’s merits (Genesis Rabbah 76:7).

ושמתי את זרעך כחול הים. וְהֵיכָן אָ"לֹ כֵן, וַהֲלֹא לֹא אָ"לֹ אֶלָּא וְהָיָה זַרְעֲךָ כַּעֲפַר הָאָרֶץ (שם כ"ח)? אֶלָּא שֶׁאָ"לֹ כִּי לֹא אֶעֱזָבְךָ עַד אֲשֶׁר אִם עָשִׂיתִי אֵת אֲשֶׁר דִּבַּרְתִּי לָךְ (שם), וּלְאַבְרָהָם אָמַר וְהַרְבָּה אַרְבֶּה אֶת זַרְעֲךָ כְּכוֹכְבֵי הַשָּׁמַיִם וְכַחוֹל אֲשֶׁר עַל שְׂפַת הַיָּם:

ושמתי את זרעך כחול הים AND I WILL MAKE THY SEED AS THE SAND OF THE SEA — Where, indeed, did God promise him this? Did he not promise him only (Genesis 28:14) “And thy seed shall be as the dust of the earth"? But the explanation is that He had at the same time promised him (Genesis 28:15) “for I will not leave thee until I have done that which I have spoken about thee”, and to Abraham he had promised (Genesis 22:17) “and I will greatly multiply thy seed as the stars of heaven and as the sand which is upon the seashore”.
