Listen up, maggots! Ezra 4 is all about your enemies givin' you grief! Yer enemies are tryin' to stop you from rebuildin' Jerusalem, so they write letters to the king and badmouth the Jews. But Artaxerxes ain't havin' it, so he sends a letter back to your enemies and tells 'em to back off. But they don't listen, and they keep messin' with ya, so the king sends another letter, this time with a big threat. But yer enemies don't listen, so the king sends another letter with a royal command to let ya build the wall. And it works! Yer enemies finally back down and leave ya alone. So, now you can get back to buildin' that wall!
