LXX Gen 23:9

καὶ δότω μοι τὸ σπήλαιον τὸ διπλοῦν ὅ ἐστιν αὐτῷ, τὸ ὂν ἐν μερίδι τοῦ ἀγροῦ αὐτοῦ· ἀργυρίου τοῦ ἀξίου δότε μοι αὐτὸ ἐν ὑμῖν εἰς κτῆσιν μνημείου.

to sell me the cave of Machpelah that belongs to him; it is at the end of his field. Let him sell it to me in your presence for full price, so that I may have a burial site.”
