Benjamin merited that the Shechinah reside in his portion. And thus you find that when Joshua apportioned Eretz Yisrael among the tribes, he left over of the choice land of Jericho five hundred ells by five hundred ells and gave a first portion to the sons of Yonadav ben Rechav from which they ate four hundred and forty years, as it is written (I Kings 6:1) "And it was in the four hundred and eightieth year after the exodus of the children of Israel from the land of Egypt … he (Solomon) built the Temple for the L-rd."
Deduct from that the forty years that Israel was in the desert, whence we find that they ate from it four hundred and forty years. And when the Shechinah reposed in the portion of Benjamin, they arose and vacated it, as it is written (Judges 1:16) "And the children of the Kenite, the father-in-law of Moses, ascended from the city of date palms" (Jericho), and (Bamidbar 10:29) "And Moses said to Chovav (Yithro) the son of Reuel the Midianite, the father-in-law of Moses … it will I give to you, etc." Now would it enter your mind that Moses was telling Yithro: Come and we will give you a portion in Eretz Yisrael?
What he was saying to him was (Ibid.) "Come with us and we will do good with you." The reference is to the choice land of Jericho, which fed the descendants of Yithro before the Temple was built for the tribes. (Ibid.) "And he said to him: 'I will not go, etc.'", viz.: In the future, when Eretz Yisrael will be apportioned among the tribes, one of them will give me one of his vineyards or one of his furrows — "but I will go to my land and eat the fruits of my land and drink the wine of my vineyard."
