"There were born to him seven sons and three daughters."
Scriptures remind us that a blessed man has a full quiver. Children are a blessing from the Lord, as any new parent can attest. I wouldn't recommend asking too many parents of teenagers though. In any case, the first pronouncement of Job's wealth, status and blessing from God begins with a list of his children. He had seven son and three daughters.
It may be that Job's wife was ungodly. It may be that like all other aspects of Job's life, his wife was a blessing too. We simply don't know. In any case, she has borne Job ten children and that much alone is more than any other Godly man I can recollect from Scripture. Job was blessed.
