Then the LORD answered Job out of the {a} whirlwind, and said,

(a) That his words might have greater majesty, and that Job might know with whom he had to do.

Wesley's Notes

38:1 Lord - The eternal word, Jehovah, the same who spake from mount Sinai. Answered - Out of a dark and thick cloud, from which he sent a tempestuous wind, as the harbinger of his presence. In this manner God appears and speaks to awaken Job and his friends, to the more serious attention to his words; and to testify his displeasure both against Job, and them, that all of them might be more deeply humbled and prepared to receive, and retain the instructions which God was about to give them.

Scofield Reference Notes

[1] The Lord answered Job

The words of jehovah have the effect of bringing Job consciously into His presence. Job 42:5. Hitherto the discussions have been about God, but He has been conceived as absent. Now Job and the Lord are face to face. It is noteworthy that Job does not answer Elihu. Despite his harsh judgment he has spoken Song truly about God that Job remains silent. Job 38:1 might be paraphrased, "Then Jehovah answered for [or on behalf of] Job."

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 38

Job 38:1-41.

1. Jehovah appears unexpectedly in a whirlwind (already gathering Job 37:1, 2), the symbol of "judgment" (Ps 50:3, 4, &c.), to which Job had challenged Him. He asks him now to get himself ready for the contest. Can he explain the phenomena of God's natural government? How can he, then, hope to understand the principles of His moral government? God thus confirms Elihu's sentiment, that submission to, not reasonings on, God's ways is man's part. This and the disciplinary design of trial to the godly is the great lesson of this book. He does not solve the difficulty by reference to future retribution: for this was not the immediate question; glimpses of that truth were already given in the fourteenth and nineteenth chapters, the full revelation of it being reserved for Gospel times. Yet even now we need to learn the lesson taught by Elihu and God in Job.

Matthew Henry's Concise Commentary

38:1-3 Job had silenced, but had not convinced his friends. Elihu had silenced Job, but had not brought him to admit his guilt before God. It pleased the Lord to interpose. The Lord, in this discourse, humbles Job, and brings him to repent of his passionate expressions concerning God's providential dealings with him; and this he does, by calling upon Job to compare God's being from everlasting to everlasting, with his own time; God's knowledge of all things, with his own ignorance; and God's almighty power, with his own weakness. Our darkening the counsels of God's wisdom with our folly, is a great provocation to God. Humble faith and sincere obedience see farthest and best into the will of the Lord.
