Suburban Banshee has a really nice Bible-language geekery post; sample here:
So the Woman of Revelation 12, previously tied to the Ark of the Covenant, is shown to be clothed with the sun — ie, showing her descent from Israel — and she has the moon under her feet — showing that she springs from Leah. All the tribes of Israel crown her. She comes from them, but she is higher in status than all of them.
That context is explained, and elaborated on.
Neat bit, I had no idea that Joseph son of Jacob’s mothers were named ‘Cow’ and ‘Ewe.’ (I like name meanings, aright?)
