Mishna, Pirkei Avot 3:17 - B

He would also say: One whose wisdom is greater than his deeds, what is he comparable to? To a tree with many branches and few roots; comes a storm and uproots it, and turns it on its face. As is stated, "He shall be as a lone tree in a wasteland, and shall not see when good comes; he shall dwell parched in the desert, a salt land, uninhabited" (Jeremiah 17:6). But one whose deeds are greater than her wisdom, to what is she compared? To a tree with many roots and few branches, whom all the storms in the world cannot budge from its place. As is stated: "She shall be as a tree planted upon water, who spreads her roots by the river; who fears not when comes heat, whose leaf is ever lush; who worries not in a year of drought, and ceases not to yield fruit" (ibid., v. 8).[Translation by chabad.org.
