Ruth's vow to Naomi is not a sentimental pledge but a costly, irreversible commitment made by an outsider with no guarantee of welcome. She binds herself to a person and to Yahweh, not to a promised outcome.

Ruth 4:13–17 credits the resolution of the story to Yahweh, not to human strategy: he enables conception, the women of Bethlehem name the child, and Naomi is publicly declared to have a restorer of life. The son born to a Moabite widow becomes the grandfather of David.
