אִם־שָׁכַ֗בְתִּי וְאָמַ֗רְתִּי מָתַ֣י אָ֭קוּם וּמִדַּד־עָ֑רֶב וְשָׂבַ֖עְתִּי נְדֻדִ֣ים עֲדֵי־נָֽשֶׁף׃
When I lie down, I say: ‘When shall I arise?’ But the night is long, and I am full of tossings to and fro unto the dawning of the day.
Rashi on Job
and the evening depart When will it become light and when will the time of arising come, and when will the evening depart? [The word מדד ] is an expression of (Gen. 31:40) “and sleep was banished (ותדד).” The “mem” is a defective radical, as in מאמר, statement; משמר, watch.
Rashi on Job
And I was sated with restlessness I was sated with restlessness on my bed by day until twilight, because, due to the torments I could not sleep until the twilight of day, since my flesh was clothed with worms.
