LXX Gen 50:5

Ὁ πατήρ με ὥρκισεν λέγων Ἐν τῷ μνημείῳ ᾧ ὤρυξα ἐμαυτῷ ἐν γῇ Χανάαν ἐκεῖ με θάψεις. νῦν οὑν ἀναβὰς θάψω τὸν πατέρα μου, καὶ ἀπελεύσομαι.

my father made me swear an oath when he said, ‘I am about to die. You must bury me in the tomb that I dug for myself in the land of Canaan.’ Now let me go and bury my father, and then return.”
