Moshe is inviting his father-in-law, Yitro, to come along with Bnei Israel to the land: אֲשֶׁר אָמַר יְקֹוָק אֹתוֹ אֶתֵּן לָכֶם, “…to the place that Hashem said ‘I shall give it to you’ ”. (Num. 10,29) He doesn’t name the place. He merely emphasizes that it is the place Hashem promised for the Jewish people. It doesn’t matter where it is. It doesn’t matter what kind of a land it is. It doesn’t matter if it has water, if it has oil or if it has other natural resources. If Hashem promised it to the Jews it has to be good.
Throughout the long Galut the Jews constantly prayed to return to this land. They knew it was a small land and that it will not be easy to gain possession of it. They were offered other lands and they rejected it. They knew the land was barren and it had no special desirable natural gifts. They knew they will find it difficult to reclaim and restore the land.
But this was the land promised to our people and it has to be here and no place else. The Jews after many centuries succeeded in getting it back against all odds and cultivated it to a point where it is a shining light for the rest of the world. From this land the Jews have made numerous contributions to the world at large.
Many in the world want to destroy it and many want to take it away from us. They will not succeed because it is the land promised our people by Hashem and it will always remain ours.
