Ruth 1:17

בַּאֲשֶׁר תָּמוּתִי אָמוּת וְשָׁם אֶקָּבֵר כֹּה יַעֲשֶׂה יְהוָה לִי וְכֹה יֹסִיף כִּי הַמָּוֶת יַפְרִיד בֵּינִי וּבֵינֵךְ׃

Rough Word-by-word:
In [the place] where you die, I will die and there I will be buried. So let do the LORD to me and so let him cause to add. For [the or this] death it [he] will cause to separate between me and between you.

A little Smoother:
Where you die, I will die and there will I be buried. Let the LORD do so to me and cause more. For this [and only this] death is what will make a separation between me and you.

Soncino's translation:
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.

Note:
There seems to be much weight behind the definite article use with "death." That along with the Hiphil "addition" indicates the need for some contextualizing of the translation.

Psalm 7:13

אִם־לֹא יָשׁוּב חַרְבֹּו יִלְטֹושׁ קַשְׁתֹּו דָרַךְ וַיְכֹונְנֶהָ׃

Rough Word-by-word:
If not he will return the sword of him he will sharpen the bow of him he has bent and he has prepared her

Smooth Translation:
If he will not return, he will sharpen his sword. He has bent his bow and prepared it

Note:
The JPS from my Soncino Psalter translates, "If man turn not, He will whet His sword, He hath bent His bow, and made it ready;"
