Isaiah tells of the birth of the Manchild, when Zion travails.

.......................Isaiah 66:6-8
6
"A voice of noise from the city, a voice from the temple, a voice of the LORD that rendereth recompence to his enemies.
7
Before she travailed, she brought forth; before her pain came, she was delivered of a man child.
8
Who hath heard such a thing? who hath seen such things? Shall the earth be made to bring forth in one day? or shall a nation be born at once? for as soon as Zion travailed, she brought forth her children."

...................The Manchild comes first; the children are those who come after.
