John Gill Commentary Ezra 7:21

"And I, even I Artaxerxes the king, do make a decree to all the treasurers that are beyond the River, that whatsoever Ezra the priest, the scribe of the law of the God of heaven, shall require of you, it be done with all diligence," — Ezra 7:21 (ASV)

shall require of you, it be done speedily ;
