Who says this, and to whom?
Radak (6-7): One who heard the rebuke of the sword (verse 6), he answers 1 .
Metzudas David: The one who rebuked, he himself answers.
"Eich Tishkoti" is second person (he addresses the sword), and "Hashem Tzivah Lah" is third person (he addresses the one who rebuked)! Radak (30:8) said that verses sometimes switch between second and third person. (PF)
What did Hashem command?
Radak: The sword must go to Ashkelon to cut it off. How can it be quiet before finishing is mission?!
Malbim: He commanded the sword to destroy kingdoms. There is another reason why it cannot be quiet; refer to 47:7:3:2.
What is the meaning of "Ye'adah"?
Radak: It was summonsed.
Malbim: (There is a natural reason why the sword cannot be quiet. Nebuchadnetzar was fighting Tzur and Tzidon, which are on the sea [shore], and Pelishtim dwell there, and helped them.) He designated [his sword to cut off shore dwellers who help Tzor].
