Job 5:12

12. Crafty From ערם , to spin, twist. Furst cites three Hebrew words expressive of cunning or evil thought, (he might have added pathal, froward, Job 5:13,) whose roots give the same idea of spinning. However men may work in the dark, spinning their evil devices, God “breaks them to pieces,” (disappointeth,) מפר .

Enterprise תושׁיה , toushiyyah. The root of the word indicates being, substance, that which is. See note on Job 6:13. It stands in contrast with און , evil, which signifies, also, emptiness, nothingness, which is its root idea. The wicked can accomplish nothing substantial.
