What is "Isya'atu"?
Rashi: They counseled.
Why did they counsel to strengthen the king's law?
Rashi: He recently began reigning, and he is from another country. He must be strengthened!
Malbim: In the first 30 days that the king was in Bavel, these Sheluchim came from all nations and Medinos. They said that they agreed to strengthen the kingdom in the eyes of all nations. During these 30 days, everyone will bring his request to the king himself. This is both in matters from a man, the king is prepared to fill every request, for he desires Chesed, and his hand is wide and open to fulfill everyone's request, and also Tefilos to Hashem. They will request from the king, for his hand is like Hashem's, to fulfill all requests 1 . One who requests from another, it is as if he denies the king's Chesed or ability.
Can the king heal all the sick, give children to all barren women, give Chochmah to simpletons, make Shalom between nations and in every family??! Even monetarily, can [or would] he fulfill every request? Everyone desires double his current wealth, and when he gets it, he desires twice that amount? (Koheles Rabah 1:1:13)! (PF)
What is the meaning of "u'Lesakafah Esar"?
Ibn Ezra: This is [to make a prohibition,] like "v'Chol Isar Asher Asrah Al Nafshah."
What law did they suggest?
Rashi: Anyone who will make any request in the coming 30 days, from anyone other than the king, he will be cast to the lions' den.
What is "Gov Aryavasa"?
Rashi: It is a pit in which the king's lions are. Ibn Ezra (13) - they cast to there Tereifos and anyone Chayav Misah.
