Daniel (Theodotion) 10:13
Swete's Septuagint · Berean Standard Bible
καὶ ὁ ἄρχων βασιλείας Περσῶν ἱστήκει ἐξ ἐναντίας μου εἵκοσι καὶ μίαν ἡμέραν· καὶ ἰδοὺ Μειχαὴλ εἰς τῶν ἀρχόντων ἦλθεν βοηθῆσαί μοι, καὶ αὐτὸν κάτελειπον ἐκεῖ μετὰ τοῦ ἄρχοντος βασιλείας ΙΙερσῶν.
However, the prince of the kingdom of Persia opposed me for twenty-one days. Then Michael, one of the chief princes, came to help me, for I had been left there with the kings of Persia.
