Some scholars have tried to prove that someone other than Nahum wrote sections of the book (1:1; 1:1-2:3; 1:2-10; 2:4-3:19), but their arguments are largely speculative. Jewish and Christian authorities have long held that Nahum was responsible for the whole work.
"Every one of the forty-seven verses of this short prophecy has been attacked by higher critics as being spurious. Contemporary critical scholarship tends to hold that at least one-third of the material was written by someone other than Nahum."2
