Midrasz do Liczb 26:38

"To these apportion the land" (Numbers 26:53). And who are they? The ones standing on the Plains of Moav. And was the land not apportioned to those that left Egypt? As it is written (Exodus 6:8), "and I will give it to you as a possession." [So] for what reason was it [actually] apportioned to [the ones standing on the Plains of Moav]? Because the Holy One, blessed be He, foresaw that six families from [those that left Egypt] would be destroyed. And who are they? [Of] those written above (Genesis 46:10), "And the children of Shimon were Yemuel, Yamin, Ohad, Yakhin, Tsohar and Shaul," when you read "to Nemuel, the Nemeulite family" (Numbers 26:12-13), neither Ohad or Tsohar are there. Rather they were lost. And so [too,] with Binyamin: "Bela, Bekher, etc." (Genesis 26:21), behold there are ten. But when you come to count them [you read], "to Belaa, the Belaaite family [etc.] (Numbers 26:38-40), they are only seven. Behold [those missing] were lost. And so [too,] with the "children of Gad. Tsifion, Chagi, Shuni, Etsbon [etc.]" (Genesis 26:16); but when you count "to Tsafon, the Tsafonite family [etc.]" (26:15-17), Etsbon is not there. Behold six families got lost from the licentiousness of the counsel of Bilaam. And there is no licentiousness that does not accomplish its [end]. Hence the Holy One, blessed be He, said, "[Why should] I apportion the land to people who will be destroyed in the future?" And [so] He [rather] apportioned it [only] to the one that stood resilient. Hence it is stated, "To these apportion the land" (Numbers 26:53).

8 "To these apportion the land" (Numbers 26:53) And who are they? The ones standing on the Plains of Moav. And was the land not apportioned to those that left Egypt? As it is written (Exodus 6:8), "and I will give it to you as a possession." [So] for what reason was it not apportioned to them? Because the Holy One, blessed be He, foresaw that families from [those that left Egypt] would be destroyed. And who are they? [Of] those written above (Genesis 46:10), "And the children of Shimon were Yemuel, Yamin, Ohad, Yakhin, Tsohar and Shaul," when you read "to Nemuel, the Nemeulite family" (Numbers 26:12-13), one is not there. And so [too,] with Binyamin: "Bela, Bekher, etc." (Genesis 26:21), behold there are ten. But when you come to count them [you read], "to Belaa, the Belaaite family [etc.] (Numbers 26:38-40), five of the sons are missing. Behold [those missing] were lost. Behold six families got lost from the licentiousness of the counsel of Bilaam. There is no [licentiousness] that does not accomplish its [end]. Hence the Holy One, blessed be He, said, "[Why should] I apportion the land to people who will be die in the future?" Once they came to the Plains of Moav, and they stood resiliently, the Holy One, blessed be He, said to him, "To these apportion the land" (Numbers 26:53).
