"And the man grew great, and went on growing greater [until he became very great]" (Genesis 26:13) until they would say, the dung of Isaac's mules, and not the silver and gold of Abimelech [is preferable]. "And he had possessions of flocks and possessions of herds and a great household [avuddah]" (Genesis 26:14). It is written "avuddah" [labor / servitude]: if a man does not make himself like a servant to it [his property], he does not acquire it. "Go from us, for you have become far mightier than we" (Genesis 26:16). He said to him: all the might you have grown was it not from us? In the past you had one little flask [kukya]; now you have many flasks. "[And Isaac's servants dug in the valley and found there a well of living water]" (Genesis 26:18-22). Rabbi Chanina said: one who sees a well in a dream sees peace, as it is said, "and Isaac's servants dug in the valley and found there a well of living water." Rabbi Natan says: he has found Torah, as it is said, "whoever finds me finds life" (Proverbs 8:35). Rava said: literally life. One who sees a well in a dream should rise early and recite "and Isaac's servants dug in the valley," before another verse precedes it [a verse of ill omen]: "as a cistern wells up its waters" (Jeremiah 6:7).
Isaac Grew Great and the Wells of Living Water
Yalkut Shimoni on Torah 111:12
(בראשית כו יג) וַיִּגְדַּל הָאִישׁ וַיֵּלֶךְ הָלוֹךְ וְגָדֵל, עַד שֶׁהָיוּ אוֹמְרִים זֶבֶל פְּרֵדוֹתָיו שֶׁל יִצְחָק, וְלֹא כַּסְפּוֹ וּזְהָבוֹ שֶׁל אֲבִימֶלֶךְ. (בראשית כו יד) וַיְהִי לוֹ מִקְנֵה צֹאן וּמִקְנֵה בָקָר וַעֲבֻדָּה רַבָּה, וַעֲבֻדָּה כְּתִיב אִם אֵין אָדָם נַעֲשֶׂה כְּעֶבֶד לְעַצְמוֹ אֵינוֹ קוֹנֶה אוֹתוֹ. (בראשית כו טז) לֵךְ מֵעִמָּנוּ כִּי עָצַמְתָּ מִמֶּנּוּ מְאֹד, אָמַר לוֹ כָּל עֲצוּמוֹת שֶׁעָצַמְתָּ, לֹא מִמֶּנּוּ הָיָה לְשֶׁעָבַר הָיָה לְךָ קווּקְיָא חַד כַּדּוֹן אִית לָךְ קווּקְיָא סַגִּיאִין. (בראשית כו יח-כב) אָמַר רַבִּי חֲנִינָא, הָרוֹאֶה בְּאֵר בַחֲלוֹם רוֹאֶה שָׁלוֹם, שֶׁנֶּאֱמַר וַיַּחְפְּרוּ עַבְדֵי יִצְחָק בַּנָּחַל וַיִּמְצְאוּ שָׁם בְּאֵר מַיִם חַיִּים, רַבִּי נָתָן אוֹמֵר, מָצָא תּוֹרָה, שֶׁנֶּאֱמַר (משלי ח, לה) מֹצְאִי מָצָא חַיִּים רָבָא אָמַר, חַיִּים מַמָּשׁ. הָרוֹאֶה בְּאֵר בַּחֲלוֹם, יַשְׁכִּים וְיֹאמַר וַיַּחְפְּרוּ עַבְדֵי יִצְחָק בַּנָּחַל, קוֹדֶם שֶׁיְּקַדְּמֶנּוּ פָּסוּק אַחֵר "כְּהָקִיר בַּוִר מֵימֶיהָ".
