Horses of the Sun:

(2Ki 23:11): In connection with the sun-worship practiced by idolatrous kings in the temple at Jerusalem (2Ki 23:5; compare Eze 8:16), horses dedicated to the sun, with chariots, had been placed at the entrance of the sacred edifice. These Josiah, in his great reformation, "took away," and burned the chariots with fire. Horses sacred to the sun were common among oriental peoples (Bochart, Heiroz., I, 2, 10).
