New Defender's Study Bible Notes
5:1 which of the saints. Although Eliphaz knew the truth about the God of creation (Job 5:9-10), he seemed also to know about angels (“saints” means “holy ones”), and to believe that they could answer prayers if they so chose. This might indicate a leaning toward pagan polytheism, a tendency that perhaps made it easier for the spirit (Job 4:15) to deceive him.
5:7 born unto trouble. Eliphaz here indicates his knowledge of the primeval curse on human birth: “In sorrow thou shalt bring forth children” (Genesis 3:16).
5:13 their own craftiness. Note I Corinthians 3:19: “For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.” Paul here acknowledges indirectly that the book of Job is a part of the inspired Scriptures. Even though God said that the counsel of Eliphaz was wrong (Job 42:7), the record of what he said was accurately recorded by divine inspiration; many of his statements are true, even though his conclusions are wrong, and the Holy Spirit was free to use and apply any of them He might choose when He later inspired Paul’s writings.
5:13 froward. “Froward” is the opposite to “to-ward;” and means “perverted” or “contrary.”
5:17 chastening of the Almighty. This is another observation by Eliphaz which the Lord has acknowledged as inspired. It is quoted, with variations, in Proverbs 3:11-12 and then with more emphasis and amplification in Hebrews 12:5-6.
5:27 for thy good. This arrogant assertion by Eliphaz indicates two things have happened previously. First, the evil spirit so impressed him with his deceptive message that Eliphaz was confident he was conveying divinely inspired advice to Job. Secondly, he had convinced Bildad and Zophar that this was the message they should unitedly give Job.
