if this city and wall are built

This can be translated in active form. See how you translated these words in Esra 4:13. Alternate translation: "if they build the city and wall" (See: rc://en/ta/man/translate/figs-activepassive)

there will be nothing remaining for you

Here "nothing" is an exaggeration to make the king think that he will be losing much tax money if the Judeans rebel. (See: rc://en/ta/man/translate/figs-hyperbole)

the Province Beyond the River

This is the name of the province that was west of the Euphrates River. It was across the river from the city of Susa. See how you translated this in Esra 4:10. (See: rc://en/ta/man/translate/translate-names)
