4 His tail drew one third of the stars of the sky, and threw them to the earth. The dragon stood before the woman who was about to give birth, so that when she gave birth he might devour her child.
a third of the stars – from Dan 8:10, the Dragon (Satan) caused some of the stars to fall to the earth. Here, we see that a third of the angels followed the lawless one. These were cast out of heaven in verse 9.
the dragon stood before the woman who was about to give birth – most immediately think of Herod’s attempt to kill the Christ Child. But the birth we are actually speaking of is described in verse 5.
