Rashi on Genesis 42:21/רש"י על בראשית מ״ב:כ״א

1אבל VERILY — It is to be understood as the Targum renders it: בקושטא “in truth”. I have seen a statement in (Genesis Rabbah 91:8) that in the Roman (Latin) language אבל means ברם (verum) truly, indeed.

2באה אלינו [THIS DISTRESS] HAS COME UPON US — The word באה has the accent upon the ב because it is the perfect tense — for it had already come upon them. The Targum therefore renders it by אתת which is a perfect tense in Aramaic — it has come.
