(Ps. XCII, 13) "Why is the righteous man compared to a palm tree? Because just as, if a palm tree is cut down, it takes a long time for one to grow again, so if the world loses a righteous man, it is a long time before another arises in his place. Further, just as a palm tree does not grow unless the male be accompanied by the female, so the righteous cannot flourish save when they are male and female together, like Abram and Sarai." - The Zohar
