Komentarz do Liczb 10:32

והיה הטוב ההוא AND IT SHALL BE THAT WHAT GOODNESS [THE LORD SHALL DO UNTO US, THE SAME WILL WE DO UNTO THEE] — What good did they actually bestow upon him (i.e. when did they redeem their promise)? They (our Sages) say: When the Israelites were parcelling out the Land the most fertile part of Jericho proved to extend over an area of 500 by 500 cubits; they left it unparcelled and said: He in whose portion of land the Sanctuary will be built shall take it as a substitute for giving up the land upon which the Temple was built. In the meantime, however, they gave it to the children of Jethro — to Jonadab the son of Rechab, [as it is said, (Judges 1:16) “And the children of the Kenite, Moses’ father-in-law, went up out of the city of the palm tree” (which is identical with Jericho; cf. Deuteronomy 34:3)] (Sifrei Bamidbar 81).

והיה כי תלך עמנו, "It will be when you come with us, etc." Why did the Torah repeat the word והיה before coming to the principal message in the verse? Besides, the entire verse seems superfluous as it contains essentially what Moses had offered Yitro already in verse 29? We will try and explain the verse both according to the view of Rabbi Eliezer Hamadoi and the view of Rabbi Joshua. According to the view of Rabbi Eliezer we must look at the word והיה as being simply a continuation of Moses' offer in verse 29 as follows: "Seeing that you have already become "our eyes," you will continue to be so when you decide to remain with us. You will most certainly not be viewed as a proselyte whose new-found enlightenment can hardly be expected to illuminate at a time when the sun of enlightenment shines all around, etc." According to the view of Rabbi Joshua, Moses merely urged Yitro to retain the stature he had acquired while on visit with the Jewish people.

A fertile area of Yericho. דושנה [means] fertile land.

אשר ייטיב ה' עמנו “the good that the Lord will do for us.” Moses refers to nations in addition to the seven Canaanite nations. He refers to Exodus 34,24: והרחבתי את גבולך, “I will expand your boundaries.” According to another view, Moses promised Yitro and his family the land belonging to the Kenites. This had been included as one of the ten nations whose lands G-d had promised to Avraham as being part of greater Israel (Genesis 15,19). This is why in future years the descendants of Yitro are usually referred to as Kenites, as for instance in Numbers 24,21, where Bileam prophesied about them. Compare also Samuel I 15,6 ויאמר שאול אל הקני, “Shaul said to the Kenite.”

According to Rabbi Eliezer the words והיה הטוב ההוא אשר ייטיב השם "the good G'd will perform with the Jewish people, etc." mean that Moses urged Yitro not to leave and to return at a later date seeing that Moses was interested that Yitro should share in the land at the time Israel would reach the land of Canaan. If he were present at that time it would be easy to grant him some of the most fertile land of that region. This could not be guaranteed if he would not be present at the time of the distribution. Actually, Yitro was persuaded by Moses argument and agreed to remain. When he found out later that the Israelites' entry into the Holy land had been postponed for 40 years, he decided to sit out this waiting period in his own country rather than in the desert. He used the interval to convert his countrymen and eventually returned to join the Jewish people and took them up on their offer. According to Rabbi Joshua our verse is also meant to tell Yitro not to view himself as inferior because he was "only" a proselyte. This is why Moses assured him that he would receive a full share of all the good G'd had in store for the Jewish people when the time came. Not only that, but he would receive of the most fertile soil that the land of Canaan had to offer.
