LXX 2 Macc 3:25

ὤφθη γάρ τις ἵππος αὐτοῖς φοβερὸν ἔχων τὸν ἐπιβάτην, καὶ καλλίστῃ σαγῇ διακεκοσμημένος, φερόμενος δὲ Ῥύθην ἔσεισεν τῷ Ἡλιοδώρῳ τὰς ἐνπροθεσίους ὁπλάς· ὁ δὲ ἐπικαθήμενος ἐφαίνετο χρυσῆν πανοπλίαν ἔχων.

For there appeared to them a horse, with a terrible rider upon him, adorned with a very rich covering: and he ran fiercely and struck Heliodorus with his fore feet, and he that sat upon him seemed to have armour of gold.
