Yes, there is a language issue. Either the command by God listed in Ezra 6:14 is a literal utterance by God or as is your view, it is figurative. Where in the text does Ezra say it wasn't a literal command?You seem to have a language issue here. The more natural meaning would exclude the way you are counting decrees here.
The more natural understanding would be that God is decreeing something *through* these earthly kings. He is using these kings as the vehicle for His own heavenly decree.
His decree is not separate, nor to be counted separately, from the decrees of these earthly kings. They are all one singular decree from God, allowing *all* of these kings' decrees to contributed to the one heavenly decree, to the one heavenly purpose, which was to rebuild both the temple and the city of Jerusalem.
You are not reading the communication properly. The result is rendering the prophecy beyond understanding, which is not what the angel means when he says details are closed off until the endtimes.
The purpose is to give enough truth to guide the People of God until the actual details come to pass. We are not to focus so much on the exact details, but on the main idea, which is to remain true to God's word until it is completely fulfilled. It is not always our purpose to actually strive to live in a time so prophesied, but rather, to prepare God's People in advance of that prophecy coming to pass.
In the same way, we preach a Kingdom that is yet to come. Our purpose is not to strive to be the Last Generation who will see this come to pass. Rather, our purpose is to preach it so that God's People can prepare now for that event.
In actual fact, there IS a literal command by God that was done. That is the entire point of the Ezra 6:14 Challenge. How does your view either address this fact or not?
