Job 38:21
Knowest thou [it], because thou wast then born? or [because] the number of thy days [is] great?
Knowest {H3045} thou it, because thou wast then born {H3205}? or because the number {H4557} of thy days {H3117} is great {H7227}?
You know, of course, because you were born then; by now you must be very old!
Surely you know, for you were already born! And the number of your days is great!
Doubtless, thou knowest, for thou wast then born, And the number of thy days is great!

Commentary
Job 38:21 is a powerful rhetorical question posed by God to Job from the midst of a whirlwind. This verse is part of a much larger divine interrogation where God challenges Job's finite understanding and wisdom, contrasting it with His own infinite knowledge and power as the Creator.
Context
This verse comes after God's dramatic appearance to Job, detailed in Job 38:1-3, where He begins to question Job about the vastness and complexity of creation. Prior to this, Job had repeatedly expressed his desire to argue his case before God, confident in his own righteousness and understanding of divine justice. God's questions, starting from the very foundations of the earth to the movements of celestial bodies and natural phenomena, are designed to humble Job and reveal the limits of human knowledge compared to the Creator's omnipotence and omniscience. Verse 21 specifically refers to Job's supposed knowledge of these grand cosmic operations, mockingly asking if he was present at creation or if his extremely long life somehow grants him such insight.
Key Themes and Messages
Linguistic Insights
The KJV's phrasing, "Knowest thou [it], because thou wast then born? or [because] the number of thy days [is] great?", uses direct and forceful rhetorical questions. The implied answer to both questions is a resounding "no." The phrase "wast then born" directly challenges Job's claim to ancient wisdom or pre-existence, while "the number of thy days is great" sarcastically dismisses the idea that even a very long life could grant insight into the mysteries of creation known only to the eternal God. The Hebrew text conveys the same sense of an impossible scenario for human knowledge.
Practical Application
Job 38:21 serves as a profound reminder for believers today:
