LXX Gen 27:41

Καὶ ἐνεκότει Ἠσαὺ τῷ Ἰακὼβ περὶ τῆς εὐλογίας ἧς εὐλάγησεν ὁ πατὴρ αὐτοῦ· εἶπεν δὲ Ἠσαὺ ἐν τῇ διανοίᾳ αὐτοῦ Ἐγγισάτωσαν αἱ ἡμέραι τοῦ πένθους τοῦ πατρός μου, ἵνα ἀποκτείνω Ἰακὼβ τὸν ἅδω φόν μου.

Esau held a grudge against Jacob because of the blessing his father had given him. And Esau said in his heart, “The days of mourning for my father are at hand; then I will kill my brother Jacob.”
