Exodus 40:13

וְהִלְבַּשְׁתָּ֙ אֶֽת־אַהֲרֹ֔ן אֵ֖ת בִּגְדֵ֣י הַקֹּ֑דֶשׁ וּמָשַׁחְתָּ֥ אֹת֛וֹ וְקִדַּשְׁתָּ֥ אֹת֖וֹ וְכִהֵ֥ן לִֽי׃

καὶ ἀλείψεις αὐτοὺς ὃν τρόπον ἤλειψας τὸν πατέρα αὐτῶν, καὶ ἱερατεύσουσίν μοι· καὶ ἔσται ὥστε εἶναι αὐτοῖς χρῖσμα ἱερατίας εἰς τὸν αἰῶνα, εἰς τὰς γενεὰς αὐτῶν.

Y harás vestir á Aarón las vestiduras sagradas, y lo ungirás, y lo consagrarás, para que sea mi sacerdote.

And you are to clothe Aaron with the holy garments, anoint him, and consecrate him, so that he may serve Me as a priest.
