Salmos 92:12-13
An old man used to say, "It is written, 'The righteous one shall blossom like the palm tree.' " Now these words make known that the soul acquires height, and straightness of stature and sweetness from beautiful deeds. But there is another quality that is found in the palm, that is, a single, white heart, which is wholly suitable for work (or useful for being worked). And this must be found in the righteous person, for his heart must be single and simple, and it must be accustomed to look toward God only. Now the heart of the palm tree is also white by reason of that fire that it possesses naturally, and all the service of the righteous person is in his heart; and the hollowness and the evenness of the tops of the leaves [typify] the setting up of sharpness of the soul of the righteous person against the calumniator. — SAYINGS OF THE FATHERS 186
