Commentaries:
By means of symbolism, Satan's position is defined in terms of attitude. Pride is rightly considered to be "the father of all sin," and the word children is used in the sense "of showing the characteristics of" or "that which is descended from." The Bible uses "sons of Belial" in a similar way. They were not literally children of Satan, but they showed the same characteristics of Satan. Literally, "foolishness" would be a better definition of Belial. We can look at our own children and see that they definitely have our physical characteristics.
So children is used in this sense: Those who are the children of Satan show his characteristics. Jesus uses the same principle back in John 8:44, when He tells the Jews that they are of their father the Devil. Satan was not their literal father, but He alludes to the fact that they displayed the spiritual characteristics of their spiritual father, Satan the Devil. Specifically, He mentions lust: "and the desires of your father you will do."
So, God says here in Job that mankind's dominant sin, idolatry, has its roots in pride. It is usually self-worship.

What I Believe About Conspiracy Theories
Are we reading here of something that could come awfully close to a fire-breathing dragon? Could this be a description possibly of Tyrannosaurus Rex? Is God describing something that Job was familiar with? Yes, He was describing something that Job was familiar with—whatever it is. If Job was not familiar with it, it would have made absolutely no sense to him.
This beast—the real king of beasts—does not fear anybody. We are looking at a description, probably figurative, of Satan the Devil in the form of a dragon, a Tyrannosaurus Rex-like symbol of Satan. The dragon is the real source of power for the Beast—a king of pride, a powerful beast beyond human control, ferocious, dangerous, repulsive, unmitigated power—the quintessential carnivore, seeking to devour.
No wonder Revelation 13:4 says, "Who can make war against the beast?" It gives every appearance of invincibility. A nasty fellow, if ever one was described. It is this beast that places its mark upon human beings. What is "the mark of the beast" in a spiritual sense? What kind of spirit emanates from this wild, ferocious, voracious system being described?
