"And he dealt well with Abram for her sake" (Genesis 12:16). A person should always be careful about wronging his wife, for since her tears come readily, the wrong done to her is great. A person should always be careful about the honor of his wife, for blessing is found in a person's house only on account of his wife, as it says, "And he dealt well with Abram for her sake." Rava said to the people of Mechoza: honor your wives, so that you may grow rich.
Honor Your Wife That You May Grow Rich
Yalkut Shimoni on Torah 68:2
(בראשית יב טז) לְעוֹלָם יְהֵא אָדָם זָהִיר בְּאוֹנָאַת אִשְׁתּוֹ שֶׁמִּתּוֹךְ שֶׁדִּמְעָתָהּ מְצוּיָה אוֹנָאָתָהּ מְרֻבָּה לְעוֹלָם יְהֵא אָדָם זָהִיר בִּכְבוֹד אִשְׁתּוֹ, שֶׁאֵין הַבְּרָכָה מְצוּיָה בְּתוֹךְ בֵּיתוֹ שֶׁל אָדָם אֶלָּא בִּשְׁבִיל אִשְׁתּוֹ, שֶׁנֶּאֱמַר, וּלְאַבְרָם הֵיטִיב בַּעֲבוּרָה. אָמַר לְהוּ רָבָא לִבְנֵי מְחוֹזָא, אוֹקִירוּ נָשַׁיְיכוּ כִּי הֵיכֵי דְתִתְעַתְּרוּ.
