Ezra 4:6

And in the reign of Ahasuerus, in the beginning of his reign,
&c.] According to Jarchi, this was Ahasuerus the husband of Esther; but, as most think ^F4, was Cambyses, the son and successor of Cyrus; so Josephus ^F5; who was an enemy to the Egyptians; and, fearing the Jews might take part with them, was no friend to them; their enemies therefore took the advantage of the death of Cyrus, and the first opportunity after Cambyses reigned in his own right:

and wrote they unto him an accusation against the inhabitants of Judah
and Jerusalem;
full of hatred and enmity, spite and malice, charging them as a turbulent, disobedient, and rebellious people.
