Short answer
– The precise human author of Job (and therefore Job 23:10–11) is unknown. Most evangelical scholars accept that the book is ancient and anonymous. Traditionally some have ascribed Job to Moses, but that is (at best) a minority view among modern evangelicals. What matters most in evangelical reading is the book’s theological message: God’s sovereignty in suffering and the believer’s refining through trials.

Why the author is uncertain (evangelical perspective)
– Internal clues: Job is set in a pre‑Israelite, patriarchal world (references to camels, lack of Israelite institutions), which suggests an early date for the events described — but that does not prove when the book was written or by whom.
– Linguistic and literary evidence: the book contains a range of Hebrew styles (prose frame and poetic discourses) and sophisticated literary art that make pinning a single author difficult.
– Ancient attributions: some Jewish and Christian traditions (and some older Christian writers) suggested Moses as the author because of the book’s antiquity and theological depth. Evangelicals respect those traditions but weigh them alongside linguistic and textual evidence; many conclude we do not have enough proof to affirm Moses (or any named person) as the writer.
– Scholarly evangelical consensus: most conservative evangelical commentators say the author is anonymous; they also often date the composition variously from the patriarchal era up through the monarchy, depending on how one weighs linguistic features and theological parallels.

Common candidate suggestions (and how evangelicals view them)
– Moses: argued for because of antiquity and thematic affinity with Exodus/the wilderness. Evangelicals who favor Mosaic authorship do so cautiously; many others find the Hebrew and theology insufficient to prove it.
– Job himself: some suggest Job could have written at least portions (e.g., his speeches), but the presence of the prose prologue/epilogue and the editorial framework argue for an editor/author who shaped the whole.
– An unknown Israelite poet or wise teacher: this is the view many evangelicals prefer — an anonymous, theologically gifted writer (possibly working with or preserving older oral traditions) composed or compiled the book.

How this affects reading Job 23:10–11 (evangelical emphasis)
– Whether written by Moses, Job, or an anonymous author, evangelical Christians read Job 23:10–11 theologically: God knows our ways and sovereignly allows testing so that faith is refined (“when he has tried me I shall come out as gold” — see 1 Peter 1:6–7; James 1:2–4). The verses emphasize personal trust, perseverance, and obedience to God’s path. Evangelicals typically apply these verses to doctrines of God’s providence, sanctification, and the refining purpose of trials.

Where to read more (evangelical resources)
– Look up evangelical commentaries and study Bibles on Job (for example, Derek Kidner’s Tyndale commentary on Job, and NIV Application or IVP treatments) and the ESV Study Bible notes, which discuss authorship issues and the theology of these verses.
