ISB ~ Revelation 12 v4

a third of the stars:A flashback to the fall of the angels at the dawn of creation (2 Pet 2:4). The imagery hints at how Satan led the rebellion, dragging a host of demons down with him (CCC 391-92). In the Bible, stars often represent angels (Rev 1:20; 9:1; Judg 5:20; Job 38:7).
