Who are "they", that should feed the woman?

Revelation 12:6 And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.

Are "they" angels, like the one who fed Elijah in I Kings 19:5-8?

Or are "they" like Obadiah, the governor of Ahab's house, who hid and fed the prophets of the LORD, in I Kings 18:4?

Or are "they" like the ravens that fed Elijah in I Kings 17:4-6?
