Louis L'Amour got this one right

Sometimes in his novels author Louis L'Amour would venture into speculation about spiritual and religious matters, and he evidently was ill-equipped to do it. However, in Jubal Sacckett, the Nachez Indian princess Itchakomi, in accepting Jubal's somewhat-indirect proposal of marriage, uses this expression: "When you wish to go to the mountains, you may go, and if you with it, I will go with you, and when you make your camp, I will cook your meat, and when you wish to sleep, I will prepare your bed. Where you go, I will go." That sounds very similar to the familiar passage from the Book of Ruth, which is frequently used in our marriage ceremonies.
