Esau's descendants have their own land, the Edom (the land of Seir), hence the Edomites. And when Moses and Joshua led the Israelites (out of Egypt and back to Canaan), the Edomites were still living in Seir or Edom. You do know the Edomites, don't you?
And if you've read all the references to Genesis, he traded his birthright to his younger twin, and then lost his blessing and inheritance to his brother, through Rebecca's manipulation. Instead of a blessing, Esau got this from his father:
Hardly, what I call a blessing.
You really haven't read any quote I had put up earlier?
You didn't read the quote that about God's covenant to Jacob?
This is why I complained about your selective reading. You don't read all the relevant verses, just the ones you think you can win an argument. Hardly what I'd call "objective scholarship".
Ok, I'll try again.
When Isaac sent Jacob back to his father's old home in Haran, to find a wife, but when he had reached Bethel, he had a vision:
Jacob returned with his whole family, about 20 years later. Just before Jacob met with Esau, at Peniel, he met an angel whom he wrestle with. The angel gave him a new name -
Israel. (Genesis 32:22-33; I am not going to quote this whole episode, so read the relevant quote.) And the meeting with Esau went well for Jacob, and Esau returned to Seir, which was to be home for his descendants - the Edomites.
Is that not clear enough for you, that Esau didn't belong in Canaan?
Later, Jacob go back to Bethel (Genesis 35
, where he had 1st had his vision of God and God's covenant, so that Jacob could built altar there.
God not only confirmed that Jacob's name would be changed to "Israel" (Genesis 35:10), but confirmed that his descendants would have Canaan (Genesis 35:12):
Do you see? God gave his promise to Abraham and to Isaac (about the land of Canaan), and now to Jacob/Israel.
Now if you have read the entire Genesis, I wouldn't even need to quote them. I am not Jewish or Christian, but even I can see it.
The land wasn't promised to the descendants of Ishmael or to the descendants of Esau.
And there are further references found in many places in the Exodus that the Israelites would eventually receive Canaan.
