Шмот 6:8 Мидраш: Midrash Tanchuma, Shemot Rabbah, Mekhilta DeRabbi Yishmael & Bamidbar Rabbah

"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).

“I appeared to Abraham” – The Holy One blessed be He said to Moses: ‘Alas for those who are lost and are not present.¹³An expression of loss over the deceased. Many times I have revealed Myself to Abraham, Isaac, and Jacob as God Almighty, but I did not make known to them that My name is the Lord as I made known to you, yet they did not question My ways. I said to Abraham: “Arise, walk through the length and the breath of the land…” (Genesis 13:17). He sought to bury Sarah and did not find a place until he purchased it, and he did not question My ways. I said to Isaac: “Reside in this land… [for I will give all these lands] to you and your descendants…” (Genesis 26:3). He sought to drink water but did not find, but rather, “the shepherds of Gerar quarreled with Isaac's shepherds, [saying: The water is ours…]” (Genesis 26:20) and he did not question My ways. I said to Jacob: “The land on which you lie [I will give to you and to your descendants]” (Genesis 28:13). He sought a place to pitch his tent but did not find until he purchased one for one hundred kesita, and he did not question my ways, and did not ask Me what My name is, as you asked.’
‘But you, at the beginning of [receiving] My mission you said to Me: What is Your name? In the end, you said: “Since I came to Pharaoh [to speak in Your name, he has harmed this people, and You did not deliver Your people]” (Exodus 5:23). Regarding that, it is stated: “I have also established My covenant…[to give them the land of Canaan…]” (Exodus 6:4), that it was given to them, as I said to them that I would give the land to them, and they did not question Me. “Moreover, I have heard the cry of the children of Israel” (Exodus 6:5) – because they did not question Me, even though Israel in that generation were not conducting themselves properly, I heard their cry because of the covenant that I had established with their ancestors.’ That is what is written: “And I have remembered My covenant” (Exodus 6:5).
“Therefore say to the children of Israel: I am the Lord, and I will take you out from under the burdens of the Egyptians, and I will deliver you from their labor, and I will redeem you with an outstretched arm, and with great judgments. And I will take you to Me as a people, and I will be to you a God; and you shall know that I am the Lord your God, who brings you out from under the burdens of Egypt ” (Exodus 6:6-7).
“Therefore [lakhen] say to the children of Israel” – lakhen is nothing other than the language of oath-taking, as it is stated: “Therefore [velakhen] I took an oath to the house of Eli” (I Samuel 3:14). The Holy One blessed be He took an oath that He would redeem them, so that Moses would not fear that perhaps the attribute of justice would delay their redemption.
“I will take you out from under the burdens of the Egyptians…” There are four redemptions here: “I will take out…I will deliver…I will redeem…I will take,” corresponding to the four decrees that Pharaoh decreed against them.¹⁴See Shemot Rabba 1:12. The four decrees are: 1) Hard labor to build the storehouse cities, 2) Killing the newborn males, 3) Casting the newborn sons into the Nile, 4) Withholding straw from brick production. Corresponding to them, the Sages instituted four cups on Passover eve, to fulfill what is stated: “I will raise the cup of salvation and call upon the name of God” (Psalms 116:13).
“And I will bring you into the land about which I raised my hand, to give it to Abraham, to Isaac, and to Jacob; and I will give it to you as a heritage; I am the Lord” (Exodus 6:8).
“And I will bring you into the land about which I raised my hand.” I will do for them what I said to your ancestors – that I would give them the Land, and they would inherit it by their [the forefathers] merit.

And it shall be when the Lord shall bring thee into the land of the Canaanite (Exod. 13:5). (Scripture mentions) five nations though there were (in fact) seven nations.¹⁷Cf. Mekhilta (Lauterbach), p. 161. Which he swore unto thy fathers to give thee (ibid.). Where did that occur? When he assured Abraham: In that day the Lord made a covenant with Abraham, saying: “Unto thy seed have I given this land” (Gen. 15:18). When he swore unto Isaac: Sojourn in this land, and I will be with thee, etc. (ibid. 26:3), and when he swore unto Jacob: The land whereupon thou liest, to thee will I give it (ibid. 28:13). Thou shalt keep this service (Exod. 13:5). That is, just as you performed this service in Egypt, so you must perform it in the generations to come. Where did He assure us that it would be? And I will bring you in unto the land, concerning which I lifted up My hand (ibid. 6:8). Into the land of the Canaanite (ibid. 13:11). Why did Canaan deserve to have the land called by his name? When Canaan heard that the Israelites were approaching, he departed from that place. The Holy One, blessed be He, said to him: Because you left that place, the land will be called by your name, and I will give you a land as beautiful as your own. What land was this? Africa. And it shall be given to thee (ibid.). This is written lest one should claim: “I inherited it from my ancestors.”
