in vain. Hebrew. tohu. Repeated from Isa_45:18. Jehovah did not command His People to seek Him in a pathless and trackless waste, where there are no indications of how He is to be found; but in His Word, where He has revealed Himself clearly and distinctly: not "in secret" or "in darkness" (same words as in Isa_45:18). Reference to Pentateuch (Deu_30:11). App-92. See note on Isa_24:10.
