Albert Barnes Commentary Job 40:1

"Moreover Jehovah answered Job, and said," — Job 40:1 (ASV)

Moreover, the Lord answered Job - The word “answered” is used here as it is often in the Scriptures, not to denote a reply to what had been immediately said, but to take up or continue an argument. What God said here was designed as a reply to the spirit which Job had so frequently manifested.
