Why does it say "v'Shafalta"?
Radak: Then you will be lowered. He addresses Yerushalayim, i.e. its residents.
Why does it say "me'Eretz Tedaberi"?
Rashi: It will seem as if the speech that leaves your mouth comes from under the ground.
Radak: You will speak in a low voice, as if it comes from under the ground.
Malbim: It is as if you speak from the ground due to your great lowliness.
What is the meaning of "ume'Afar Tishach"?
Radak: The matter is repeated in different words.
What is the meaning of "v'Hayah k'Ov me'Eretz Kolech"?
Radak: The matter is repeated again in different words. Ba'alei Ov (conjurers) emit a low noise from below the ground, like I explained in Shmuel I, 28:24.
Malbim: It is not human speech, rather, from a dead body in which a Neshamah was cast temporarily.
What is the meaning of "Imrasech Tetzaftzef"?
Rashi: You will supplicate to Me, and amidst this, My mercy will be aroused. Tziftzuf is a whisper, like the voice of small birds.
Radak: Tetzaftzef begins with Tov, for it is third person feminine; it refers to Amirah, like Tishach. It will be so low that it will not resemble human speech, rather, chirping of birds. This refers to Elyakim, Shevna and Yo'ach, who said to Ravshake "speak to your servants in Arame'ic, and do not speak in Yehudis in the ears of this nation" (36:11). They spoke to him in a low voice, so the people would not hear.
