A parable of a king, who had dispute and war with the ‘70 nations’, and no-one knew who had won the dispute. And they asked him the king: ‘who was victorious in the dispute?’ He said: ‘Look at those who are depicted, with weapons of war in their hands, and you will know who has won the dispute.’lxviiiSee Vayiqra Rabbah 30:2.
And you shall take for yourselves, on the first day, the fruit of a stately tree... – this is the citron (etrog), which is the Shekhinah, the heart,lxixVayiqra Rabbah 30:14 which is the primary of all the limbs of the body, which are three strands of myrtle (hadas), and the palm-branch (lulav), and two strands of willow (’aravah) – the heart is in the middle, and the limbs are round about it. And thus, the etrog is the Shekhinah.
