Mark 10:40
Patriarchal Greek New Testament (1904) · Berean Standard Bible
τὸ δὲ καθίσαι ἐκ δεξιῶν μου καὶ ἐξ εὐωνύμων οὐκ ἔστιν ἐμὸν δοῦναι, ἀλλ᾽ οἷς ἡτοίμασται.
But to sit at My right or left is not Mine to grant. These seats belong to those for whom (note: Literally Mine to grant, but for whom) they have been prepared.”
