'Kingdom' in the Bible

Now in the first year of Cyrus, king of Persia, in order that the word of the Lord given by the mouth of Jeremiah might come true, the spirit of Cyrus, king of Persia, was moved by the Lord, so that he made a public statement through all his kingdom, and put it in writing, saying,

Now these are the people of the divisions of the kingdom, among those who had been made prisoners by Nebuchadnezzar, king of Babylon, and taken away to Babylon, who went back to Jerusalem and Judah, everyone to his town;

And now it is my order that all those of the people of Israel, and their priests and Levites in my kingdom, who are ready and have a desire to go to Jerusalem, are to go with you.

Whatever is ordered by the God of heaven, let it be done completely for the house of the God of heaven; so that there may not be wrath against the kingdom of the king and his sons.
