▼ The Piel of חָתַת (khatat) occurs only here and in Jer 51:56 (where it is doubtful). The meaning is clearly “startle, scare.” The perfect verb with the ו (vav) is fitting in the apodosis of the conditional sentence.

▼ Here Job is boldly saying that it is God who is behind the horrible dreams that he is having at night.

▼ The Piel of בָּעַת (ba’at, “terrify”) is one of the characteristic words in the book of Job; it occurs in 3:5; 9:34; 13:11, 21; 15:24; 18:11; and 33:7.

▼ The prepositions בּ (bet) and מִן (min) interchange here; they express the instrument of causality. See N. Sarna, “The Interchange of the Prepositions bet and min in Biblical Hebrew,” JBL 78 (1959): 310-16. Emphasis on the instruments of terror in this verse is highlighted by the use of chiasm in which the prepositional phrases comprise the central elements (ab//b’a’). Verse 18 contains another example.
