¹ tn The particle אוּלָם (’ulam, “but”) serves to restrict the clause in relation to the preceding clause (IBHS 671-73 §39.3.5e, n. 107).

¹ tn Heb “Thus may the Lord do to me and thus may he add…” The construction וְכֹה יֹסִיף…כֹּה יַעֲשֶׂה (koh ya’aseh...vÿkhoh yosif, “May he do thus…and may he do even more so…!”) is an oath formula of self-imprecation (e.g., 1 Sam 3:17; 14:44; 20:13; 25:22; 2 Sam 3:9,35; 19:14; 1 Kgs 2:23; 2 Kgs 6:31). In this formula the exact curse is understood but not expressed (GKC 472 §149.d; BDB 462 s.v. כֹּה 1.b). In ancient Near Eastern imprecations, when the curse was so extreme, it was not uttered because it was unspeakably awful: “In the twelve uses of this formula, the calamity which the speaker invokes is never named, since OT culture (in keeping with the rest of the ancient Near East) accorded such power to the spoken word” (F. W. Bush, Ruth, Esther [WBC], 82). Ruth here pronounces a curse upon herself, elevating the preceding promise to a formal, unconditional level. If she is not faithful to her promise, she agrees to become an object of divine judgment. As in other occurrences of this oath/curse formula, the specific punishment is not mentioned. As Bush explains, the particle כִּי (ki) here is probably asseverative (“indeed, certainly”) and the statement that follows expresses what underscores the seriousness of her promise by invoking divine judgment, as it were, if she does otherwise. Of course, the Lord would not have been obligated to judge her if she had abandoned Naomi – this is simply an ancient idiomatic way of expressing her commitment to her promise.
