If ever there was a key to unraveling Old Testament scripture, it is the Cyrus Cylinder. Comparing passages in 2nd Chronicles, Ezra, Isaiah, and Daniel, to what the cylinder actually states, we can see how the Jews took reality and recast it to glorify their tribal god. One example of what the cylinder says versus the Biblical rendition: Cylinder: "Marduk, the great lord, bestowed on me as my destiny the great magnanimity of one who loves Babylon, and I every day sought him out in awe." Isaiah 45:1 "Thus saith the Lord to his anointed (messiah), to Cyrus, whose right hand I have holden, to subdue nations before him..."
The formula in the Old Testament (indeed, everywhere in Mesopotamia) was victory is caused by the power of the deity, whereas defeat came by way of defective, unfaithful humans. Reading (1st or 2nd) Kings or Chronicles, the formula becomes downright tedious. It is like the boss who takes personal credit for any successful project, but vehemently denounces his staff when things are delayed or messed up. Anyone like working for that type of boss? Then why would you have him as your God?
