How do they profane Hashem to His nation?
Radak: This is like b'Ami. Also "v'El ha'Aron Titen Es ha'Edus" (Shemos 25:21) is like uva'Aron. The Chilul is that they remove their trust from Me, and trust in their ways of Sheker.
Malbim: They made the Kedushah of My name Chulin [for the food that they give to you].
What are "b'Sha'alei Se'orim uvi'Fsosei Lechem"?
Rashi: Sha'alei is like "Mi Madad b'Sha'alo Mayim" (Yeshayah 40:12); they are measures. Pesosei Lechem are pieces [of bread, that you receive for your wages].
Radak #1: These are your wages. Those who ask you give to your wages ? a handful of barley or bread.
Radak #2: They put barley and bread in the pillows, and did their actions with them.
What is the meaning of "Lehamis Nefashos Asher Lo Semusenah u'Lechyos Nefashos Asher Lo Sichyenah"?
Rashi: To say about Nefashos that you do not kill ? they will die, and to say about those that you do not sustain ? they will live. I.e. your divining is Sheker, and My nation accepts your false predictions.
Radak: This refers to Nefashos of Tzadikim, and Nefashos of Resha'im, respectively. You do not sustain or kill them via words. You lie to those in My nation who hear Sheker.
Malbim #1: They make people die death of the Nefesh, and via this you sustain yourselves.
Malbim #2: You prophesize that Tzadikim will die, and Resha'im will live.
Who are "Shome'ei Chezev"?
Malbim: My nation accepts your lies and false beliefs.
