בַּאֲשֶׁ֤ר תָּמ֙וּתִי֙ אָמ֔וּת וְשָׁ֖ם אֶקָּבֵ֑ר כֹּה֩ יַעֲשֶׂ֨ה יְהוָ֥ה לִי֙ וְכֹ֣ה יֹסִ֔יף כִּ֣י הַמָּ֔וֶת יַפְרִ֖יד בֵּינִ֥י וּבֵינֵֽךְ׃
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.’
Rashi on Ruth
So may Adonoy do to me. As He has begun to afflict [me], for His hand has gone forth against me to kill my husband and to cause me to lose my possessions.
Rashi on Ruth
And even more. If anything but death separates me from you.
