Midrasch zu Bereschit 23:5

6) R Yossi Haglili says: After Scripture equates the deed of the land of Egypt with that of the land of Canaan, and that of the land of Canaan with that of the land of Egypt, why did the Canaanites merit remaining in their land for forty-seven years, as it is written (Bamidbar 13:22) "And Chevron (in Canaan) was built seven years before Tzoan (in) Egypt" (and add forty years for their sojourn in the desert)? It was because they honored our father Abraham, saying (Bereshith 23:5) "Hear us, my lord, a prince of G d are you in our midst" — wherefore they merited remaining on their land forty-seven years.

Another interpretation (of Prov. 3:4): SO YOU SHALL FIND GRACE. This is Abraham, who was pleasing to mortals and to angels. Thus it is stated (in Gen. 23:6): HEAR ME, MY LORD < ABRAHAM >, YOU ARE A PRINCE OF GOD IN OUR MIDST. Ergo, < he was pleasing > to mortals. Where is it shown < that he was pleasing > to the Holy One and to angels? Where it is stated (in Gen. 18:17): THEN THE LORD SAID: SHALL I HIDE FROM ABRAHAM < WHAT I AM DOING > ?

And Avraham rose from his dead (Genesis 23:3) - it teaches us that he was able to see the angel of death defying him. Rabbi Yochana said: from here we teach: 'a person whose dead lies before them is exempt from saying the Shema, from Prayer and from putting tefilin and from all the mitzvot contained in the Torah - this comes from here, he rose and spoke. 'A stranger and a resident' - a stranger that lives there, a resident that is the master of this house. If you want, I am a stranger, if not, I am a master of this house, since the Holy One of Blessing said to me "this land I will give to your seed" (Genesis 15:18). "Give me a piece of burial to bury my dead" - I only request space for one dead, as it is written "give me one piece for burial place." "And the children of Chet answered to Avraham... listen to us, lord, etc" (Genesis 23:5-6): you are a king for us, you are a prince for us, you are a god for us. He said to them: do not detract His kingship from this world, do not detract His Divinity from the world. "in our choicest plots, bury your dead" - many dead. "And Avraham prostrated" - from here you learn that we give thanks for good news.
