Matthew Poole and continuators on Daniel 6:15

15 Then these men assembled unto the king, and said unto the king, know, O king , that the law of the Medes and Persians is, that no decree nor statute which the king establisheth, may be changed .

These were bold men they were resolved to follow their blows, and would have their will rather then the King should have his in this case, which on the Kings part was honourable, and royal to retrive an evil act, and to retract, at least to mitigate a rigid, and rash Decree.

Thus Haman contrived, and pleaded, yet there was a way found to prevent execution. Esther 8. Again this Law which they plead was fundamental to make all Lawes and Decrees immutable, was absurd, and impolitick; for Laws should be essentially changeable by the Lawmakers▪ because they often see greater cause to change a Law when it grows obsolete, and burdensome, though before thought necessary then to make it at first: whereof we have sufficient instances in all Nations in all ages. Will any Legislative power in the World so bind their own hands as to entail a yoke upon themselves and nation, which they and posterity could not remedy, the intent of the Lawgiver is the Law, the equity of it is the obligation of it, which also is the true measure of its duration.
