General Information:

Zophar continues speaking with Job.

Do you not know this fact from ancient times ... for a moment?

Zophar uses a rhetorical question to cause Job to think deeply about what he will now say. This can be translated as a statement. Alternate translation: "Surely you know what has been true since the ancient times ... for a moment." (See: rc://en/ta/man/translate/figs-rquestion)
