The Sign's Explanation Names Exile and Inherited Practice

Hearers will ask why, and the answer names forsaking and worse present practice

And it shall come to pass, when thou shalt shew this people all these words, and they shall say unto thee, Wherefore hath the LORD pronounced all this great evil against us? or what is our iniquity? or what is our sin that we have sinned against the LORD our God? Then shalt thou say unto them, Because your fathers have forsaken me, saith the LORD, and have walked after other gods, and have served them, and have worshipped them, and have forsaken me, and have not kept my law; And ye have done worse than your fathers; for, behold, ye walk every one after the imagination of his evil heart, that they may not hearken unto me.

Ancestral language does not make guilt hereditary. The present generation is charged with doing worse, which is about practice, not blood. The question 'what is our sin?' is answered with forsaking and refusal to hear, not with a racial stain.

Expulsion to an unknown land is the explained sign

Therefore will I cast you out of this land into a land that ye know not, neither ye nor your fathers; and there shall ye serve other gods day and night; where I will not shew you favour.

The explanation must not justify blaming displaced people for their trauma. Serving other gods in a foreign land is this oracle's bitter irony, not a theory that every migrant is being punished.
