Genesis 23:4

גר ותושב אנכי עמכם I AM A STRANGER AND A SETTLER WITH YOU — A stranger having come from another land, but I have settled down amongst you. A Midrashic explanation is: if you agree to sell me the land then I will regard myself as a stranger and will pay for it, but if not, I shall claim it as a settler and will take it as my legal right, because the Holy One, blessed be He, said to me, (12:7) “Unto thy seed I give this land" (Genesis Rabbah 58:6). אחזת קבר A POSSESSION OF A BURYING PLACE — means possession of land to serve as a burying place.

גֵּר־וְתוֹשָׁ֥ב אָנֹכִ֖י עִמָּכֶ֑ם תְּנ֨וּ לִ֤י אֲחֻזַּת־קֶ֙בֶר֙ עִמָּכֶ֔ם וְאֶקְבְּרָ֥ה מֵתִ֖י מִלְּפָנָֽי׃

I am a stranger and a sojourner with you: give me a possession of a buryingplace with you, that I may bury my dead out of my sight.
