Job 27:12

If you yourselves have all seen this, Why in the world ¹  do you continue this meaningless talk? ² 

Job 6:25-29; Job 13:4-9; Job 16:3; Job 17:2; Job 19:2,3; Job 21:3; Job 21:28-30; Job 26:2-4; Ec 8:14; Ec 9:1-3

¹ tn The interrogative uses the demonstrative pronoun in its emphatic position: “Why in the world…?” (IBHS 312-13 §17.4.3c).

² tn The text has the noun “vain thing; breath; vapor,” and then a denominative verb from the same root: “to become vain with a vain thing,” or “to do in vain a vain thing.” This is an example of the internal object, or a cognate accusative (see GKC 367 §117.q). The LXX has “you all know that you are adding vanity to vanity.”
