Ruth 1:15, 16, 17, 18

And she said, Behold, thy sister-in-law is gone back unto her people, and unto her gods: return thou after thy sister-in-law.

And Ruth said, Entreat 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 aught but death part thee and me.

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