Ruth 1:18

16And Ruth said, Intreat me not to leave thee, or to return from following after thee: for whither thou goest, I will go; and where thou lodgest, I will lodge: thy people shall be my people, and thy God my God:

17Where thou diest, will I die, and there will I be buried: the LORD do so to me, and more also, if ought but death part thee and me.

18When she saw that she was stedfastly minded to go with her, then she left speaking unto her.

19So they two went until they came to Bethlehem. And it came to pass, when they were come to Bethlehem, that all the city was moved about them, and they said, Is this Naomi?

20And she said unto them, Call me not Naomi, call me Mara: for the Almighty hath dealt very bitterly with me.
