As a matter of fact, in the Holy Scriptures, consistency, cohesion and coherence among texts can serve as evidence for the oneness of source and sound ascription. On the contrary, the inconsistency and incoherence of texts can serve as evidence for the multiplicity of sources and false ascription.
Therefore, some of the many proofs of the oneness of the source of the Qur’an and its sound ascription to God are the consistency, cohesion and coherence among its texts. About that, in the Qur’an, God says:
Then do they not reflect upon the Qur’an if it had been from [any] other than Allah they would have found within it much contradiction (An-Nisa 4:82)
On the contrary, when it comes to the Bible, some of the ample proofs of the multiplicity of its sources and the invalid ascription of a good deal of its contents to God are the remarkable contradictions, inconsistencies and discrepancies among its verses, chapters and books both in the Old Testament and the New Testament.
Indeed, the Bible contradictions, inconsistencies and discrepancies are uncountable. Therefore, we content ourselves with the most important biblical contradictions, inconsistencies and discrepancies which do not require check, scrutiny or verification. You will find manifest contradictions which catch the eye at first blush. So, they do not need argumentation, evidence or even study.
At last, God was right when He said that his truly pure words are free from contradictions and inconsistencies. As for God’s words mixed with men’s words, they abound in many contradictions and inconsistencies.
