'Precisely' in the Bible

"I, King Artaxerxes, hereby issue orders to all the treasurers of Trans-Euphrates, that you precisely execute all that Ezra the priestly scribe of the law of the God of heaven may request of you --

Everything that the God of heaven has required should be precisely done for the temple of the God of heaven. Why should there be wrath against the empire of the king and his sons?
