The Rise Up Singing Songbook (page 249) has a nice song set to the melody of Jacob's Ladder." It's called "Sarah's Circle," and I'm wondering what's the significance of the term "Sarah's Circle." Sarah was the wife of Abraham and mother of Isaac, but I don't remember a circle in the story of Sarah.

SARAH'S CIRCLE
(Carol Etzler)

We are weaving [dancing] Sarah's circle (2x)
Sisters one and all [Sisters, brothers all]

We will all do our own naming (2x) Sisters....

Every round a generation

Here we seek and find our history [future]

On and on the circle's moving

We are open, we are shining!



Tune: Jacob's ladder

So, does anyone know the significance of the term "Sarah's Circle"?
