'Mother's' in the Bible

"Listen to me, you coastlands! Pay attention, you people from far away! The LORD called me from the womb; while I was still in my mother's body, he pronounced my name.

This is what the LORD says: "Where is your mother's certificate of divorce with which I sent her away? Or to which of my creditors did I sell you? Look! It's because of your sins that you were sold, and because of your transgressions that your mother was sent away.
