The idea of Christ being begotten in an act of conception is carried forward with the analogy of the labor of childbirth. As such, the Son was brought forth as if a baby was being born.
Childbirth
Labor Pains
We (that's me and the Holy spirit) only know what we've been told, but everything that we've been told has been given us for a reason. We may ask: what does a prophetic vision of a war in heaven have to do with events on the Earth?
Weep and Howl
Go to now, ye rich men, weep and howl for your miseries that shall come upon you.
Brought forth: חוֹלָ֑לְתִּי – cholalti
We've resolved what popular science (SciPop) calls "the Big Bang" with nucleosynthesis as described in Genesis 1:3. However, it would seem that before the Big Bang there was a Loud Howl.
Hō·w·lā·lə·tî
God the Son was begotten in an act of conception. It's part of the meaning of the Greek phrase the foundation of the world. The same event is rendered from Hebrew as childbirth, where we get the word howl.
