387. Rabbi Aba said, This matter REGARDING THE PHILISTINE has not suited me, and I need to study it further. Rabbi Elazar said, It is definitely so. This Philistine was close to the lineage of David and was the son of Orpah. That is the meaning of what is written: "Out of the ranks (Heb. ma'arachot) of the Philistines" (I Shmuel 17:23). Do not pronounce "ma'arachot," but read 'from the caves (Heb. me'arot) of the Philistines,' because he caused shame to his mother, making her as a cave, because it is written: "And the Philistine cursed David by his Elohim" (Ibid. 43). David gazed at him with an evil eye and anywhere THAT DAVID was gazing with an evil eye, all kinds of leprosy flowed from the eyes of David. This is the way it was regarding Joab. As soon as David gazed at him with an evil eye, it is written: "And let the house of Joab never lack such as are afflicted with an issue, or with leprosy..." (II Shmuel 3:29).

From that cave will emanate a fire to burn the world. And from that cave will grow one great lofty branch that will dominate over the entire world, and the kingdom will be granted to him. The most high saints will be gathering to him. Then, Messiah will be revealed in the entire world and the kingdom will be granted to him.
