'Diligently' in the Bible

And I, I Artaxerxes the king, do give orders to all the treasurers that are beyond the river, that whatever Ezra the priest and scribe of the law of the God of the heavens shall require of you, it be done diligently,

And whosoever will not do the law of thy God and the law of the king, let judgment be executed diligently upon him, whether unto death, or to banishment, or to confiscation of goods, or to imprisonment.
