12 This is the main clause, and not part of the previous conditional clause; it is introduced by the conjunction אִם (’im) (see §112.gg).
13 The verb מָדַד (madad) normally means “to measure,” and here in the Piel it has been given the sense of “to extend.” But this is not well attested and not widely accepted. There are many conjectural emendations. Of the most plausible one might mention the view of Gray, who changes מִדַּד (middad, Piel of מָדַּד) to מִדֵּי (midde, comprising the preposition מִן [min] plus the noun דַּי [day], meaning “as often as”): “as often as evening comes.” Dhorme, following the to some extent, adds the word “day” after “when/if” and replaces מִדַּד (middad) with מָתַי (matay, “when”) to read “If I lie down, I say, ‘When comes the morning?’ If I rise up, I say, ‘How long till evening?’ ” The , however, may be based more on a recollection of Deut 28:67. One can make just as strong a case for the reading adopted here, that the night seems to drag on (so also ).
14 The Hebrew term נְדֻדִים (nédudim, “tossing”) refers to the restless tossing and turning of the sick man at night on his bed. The word is a derived from the verb נָדַד (nadad, “to flee; to wander; to be restless”). The plural form here sums up the several parts of the actions ( §144.f). E. Dhorme (Job, 99) argues that because it applies to both his waking hours and his sleepless nights, it may have more of the sense of wanderings of the mind. There is no doubt truth to the fact that the mind wanders in all this suffering; but there is no need to go beyond the contextually clear idea of the restlessness of the night.
