וַיְהִ֛י מִקֵּ֥ץ יָמִ֖ים וַיִּיבַ֣שׁ הַנָּ֑חַל כִּ֛י לֹֽא־הָיָ֥ה גֶ֖שֶׁם בָּאָֽרֶץ׃ (ס)
땅에 비가 내리지 아니하므로 얼마 후에 그 시내가 마르니라
Rashi on I Kings
The brook dried up. In order that he realize the need for rain and trouble himself to go into exile, for it was displeasing to the Holy One Blessed Is He, that Yisroel should be living in hunger.5See Maseches Sanhedrin 113a and Rashi there.
