Ruth 1:21 (KJV)

And 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:

Where 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.

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

So 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?

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

So Naomi returned, and Ruth the Moabitess, her daughter in law, with her, which returned out of the country of Moab: and they came to Bethlehem in the beginning of barley harvest.
