The Manchild doesn't represent all of the Woman's children. There are others of her seed.



...........The Manchild holds the main position. The Manchild [the first of the First-fruits] is born almost before the travailing begins.


...................The children [the Harvest] are born during the travailing.

......................Revelation 12:5-6
5 "And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.
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."
