Jeremiah 32:23

And they came in, and possessed it; but they obeyed not thy voice, neither walked in thy law; they have done nothing of all that thou commandedst them to do: therefore thou hast caused all this evil to come upon them:

They have done nothing of all that thou commandedst ... therefore thou hast caused all this evil. Their punishment was thus exactly commensurate with their sin. It was not fortuitous.
