Job 9:5

He who removes mountains suddenly, ¹  who overturns them in his anger; ² 

Nu 1:5,6; Job 28:9; Ps 46:2; Ps 68:8; Ps 114:6; Isa 40:12; Hab 3:6,10; Zec 4:7; Zec 14:4,5; Mt 21:21; Mt 27:51; Lu 21:11; 1Co 13:2; Re 6:14; Re 11:13; Re 16:18-20

¹ tn The verb is plural: “they do not know it.” This suggests that the mountains would not know it. Some follow the Syriac with a singular verb, i.e., God does not know it, meaning, it is so trifling to God that he can do it without thinking. But the better interpretation may be “suddenly.” This would be interpreted from the MT as it stands; it would imply “before they know anything,” thus “suddenly” (Gray, Dhorme, Buttenwieser, et. al.). D. W. Thomas connects the meaning to another verb based on Arabic and translates it, “ so that they are no longer still” (“Additional Notes on the Root yada` in Hebrew,” JTS 15 [1964]: 54-57). J. A. Emerton works with a possible root יָדַע (yada’) meaning “be still” (“A Consideration of Some Alleged Meanings of yada` in Hebrew,” JSS 15 [1970]: 145-80).

² sn This line beginning with the relative pronoun can either be read as a parallel description of God, or it can be subordinated by the relative pronoun to the first (“they do not know who overturned them”).
