▼ There is no indication that this clause is to be subordinated to the next, other than the logical connection, and the use of the ו (vav) in the second half.

▼ See Job 19:3.

▼ The phrase actually has רוּחַ מִבִּינָתִי (ruakh mibbinati, “a spirit/wind/breath/impulse from my understanding”). Some translate it “out of my understanding a spirit answers me.” The idea is not that difficult, and so the many proposals to rewrite the text can be rejected. The spirit of his understanding prompts the reply.

▼ To take this verb as a simple Qal and read it “answers me,” does not provide a clear idea. The form can just as easily be taken as a Hiphil, with the sense “causes me to answer.” It is Zophar who will “return” and who will “answer.”
