John Gill Commentary Daniel 6:9

"Wherefore king Darius signed the writing and the interdict." — Daniel 6:9 (ASV)

Wherefore King Darius signed the writing and the decree . Moved to it by the number and importunity of his principal men; and chiefly through affectation of deity, which this law gave him; and that he might have an opportunity of ingratiating himself into his new subjects by his munificence and liberality, not being aware of the snare laid for his favourite, Daniel.
