Job 4:13 New English Translation

¹³In the troubling thoughts^[a] of the dreams^[b] in the night
when a deep sleep^[c] falls on men,

Job 4:13 tn Here too the word is rare. The form שְׂעִפִּים (s^eʾippim, “disquietings”) occurs only here and in 20:2. The form שַׂרְעַפִּים (sarʿappim, “disquieting thoughts”), possibly related by dissimilation, occurs in Pss 94:19 and 139:23. There seems to be a connection with סְעִפִּים (s^eʿippim) in 1 Kgs 18:21 with the meaning “divided opinion”; this is related to the idea of סְעִפָּה (s^eʿippah, “bough”). H. H. Rowley (Job [NCBC], 47) concludes that the point is that like branches the thoughts lead off into different and bewildering places. E. Dhorme (Job, 50) links the word to an Arabic root (“to be passionately smitten”) for the idea of “intimate thoughts.” The idea here and in Ps 139 has more to do with anxious, troubling, disquieting thoughts, as in a nightmare.
Job 4:13 tn Heb “visions” of the night.
Job 4:13 tn The word תַּרְדֵּמָה (tardemah) is a “deep sleep.” It is used in the creation account when the Lord God caused a deep sleep to fall on Adam; and it is used in the story of Jonah when the prophet was asleep during the storm. The LXX interprets it to mean “fear,” rendering the whole verse “but terror falls upon men with dread and a sound in the night.”
