Komentaryong Sumisipi para sa Mga Bilang 34:16

כל נשיא בהם. The principal meaning of the verse is as follows: you should take as the twelve representatives, one of each tribe, men whose heart was set on going on to the Holy Land. You should select volunteers, willing to act as spies. From among all these volunteers you are to select the ones who appear most suitable to you. Seeing that what was required were stout-hearted men, physically strong so that they could carry with them samples of the produce of the land, G’d did not mention them by name, as He had done when he appointed the 12 princes who were to be leaders of each tribe. G’d also appointed by name the next generation of such tribal princes, the ones who would enter the Holy Land together with their respective tribes.
