And they lifted up their voice, and wept again:
and Orpah kissed her mother in law;
but Ruth clave unto her.
And she said, Behold,
thy sister in law is gone back unto her people,
and unto her gods:
And Ruth said, Intreat me not to leave thee,
or to return from following after thee:
Ruth 1:14-16
At the 2nd Advent......
Two women shall be grinding at the mill;
the one shall be taken, and the other left.
Matthew 24:21
