Ruth 1:14-16

14 And they lifted up their voices, and wept again. And Orpah kissed her mother-in-law, but Ruth clung to her.

15 And she said, Behold, thy sister-in-law has gone back to her people, and to her god. Return thou after thy sister-in-law.

16 And Ruth said, Entreat me not to leave thee, and to return from following after thee, for where thou go, I will go, and where thou lodge, I will lodge. Thy people shall be my people, and thy God my God.
