Radak #1: Ravshake rebuked us with words of blasphemy.

Radak #2: Hashem rebukes us for our sins.

Radak citing Targum Yonasan: It is shame.

Malbim (Yeshayah 37:3): He argues and 'proves' that Hashem cannot save. If He does not save, they will say that it is because He lacks power!

Radak (Yeshayah 37:3): It is an adjective (the Ko'ach is what is needed for birth).

Radak citing Targum Yonasan (Yeshayah 37:3): It is to give birth.
