What is the meaning of "ha'Yintor l'Olam"?
Rashi (4): If you would repent, will your Master bear a grudge forever for your sin against Him? He will not bear it forever.
Radak citing his father: The people said so (will Hashem bear a grudge forever)? The Navi answered them, "you said and did evil, and succeeded."
Malbim: You say so when rain is withheld, that I am Aluf Ne'urecha, and I cannot hate you forever.
Why is it written Dibarti, and we pronounce it Dibart?
Rashi: The pronunciation teaches that you said 'we will not come to you again.' You will do that evil and not put your heart to repent.
Radak: The Kesiv means that I told you to repent, but you did not. The pronunciation teaches that you said to do evil, and you did like you said!
Malbim: The pronunciation teaches that you said that Hashem will not punish. Still, you did not cease your evil deeds.
Why does it say "va'Tuchal"?
Rashi: You succeeded to rebel.
Radak citing Targum Yonasan: You did as much evil as you could.
Radak: You did evil when you were able to. The prefix Vov is in place of Ka'asher, like "Im Lo Yisbe'u va'Yalinu", "v'Sifsei Chachamim Renanos Yehalel Pi" (Tehilim 59:16, 63:6).
Sha'arei Teshuvah 1:5: Evil became like Heter in your eyes, and like something in your ability and Reshus. This is like "Lo Suchal Le'echol bi'She'arecha" (Devarim 12:17); the Targum is, you are not permitted.
Malbim: You are able to do the deeds of an assertive harlot; she refuses to be ashamed.
Why does it say "va'Ta'asi" (feminine) and "va'Tuchal" (masculine)?
Radak: Verses often do so when discussing Keneses Yisrael. They use the feminine for Keneses, and the masculine for ha'Am.
