Who is speaking?
Radak: The Navi speaks on behalf of Yisrael, who scream about the extortion of Bavel.
Radak citing Targum Yonasan: Yerushalayim says, Nebuchadnetzar Melech Bavel plundered my property, destroyed me, broke me like an empty Kli, swallowed me like a snake, filled his treasure house from the good of my land, and dislocated me.
What is the meaning of "Achalni"?
Malbim: Bavel killed my (Tziyon's) people in the days of Yehoyakim.
Why are the five verbs in this verse written with a Vov at the end, and we pronounce them with a Yud?
Radak: The Kesiv is in the plural corresponding to the individuals. The writing is singular, corresponding to the Klal.
What is the meaning of "Hamemani"?
Radak: This is like "v'Hamam Gilgal Eglaso" (Yeshayah 28:28), i.e. breakage.
What is the meaning of "Hatzigani Kli Rik"?
Radak: He emptied me like an empty Kli. Rik is like Reik. It is a noun, as if it says Kli Reikos (a Kli of vanity; it does not hold anything).
Malbim: He exiled them with Yechanyah.
What is the significance of swallowing like a snake?
Malbim: He plundered all that they had.
What is the meaning of "Malei Chereso me'Adanai"?
Radak: This is a metaphor. He filled his land from my good (property).
Why does it say "Hidichani"?
Radak: This is like one who rinses a Kli, so nothing will remain in it.
Malbim: He totally cast them off in the exile of Tzidkiyah.
