הָיִ֧יתִי בַיּ֛וֹם אֲכָלַ֥נִי חֹ֖רֶב וְקֶ֣רַח בַּלָּ֑יְלָה וַתִּדַּ֥ד שְׁנָתִ֖י מֵֽעֵינָֽי׃
Так я и был: днем меня поглотила засуха, а ночью был мороз; и мой сон скрылся от моих глаз.
Rashi on Genesis
אכלני חרב THE DROUGHT CONSUMED ME — the same metaphor as (Deuteronomy 4:24) אש אכלה “a consuming fire”.
Radak on Genesis
הייתי, seeing that I did not want to entrust the flock to another shepherd, I was forced to endure the sun’s heat by day and the extreme cold at night. I denied myself sleep at night for fear something could happen to any of the animals.
Siftei Chakhamim
The same meaning as a consuming fire. אוכלה denotes destruction (כלייה), [not eating (אכילה)].
