Rashi on Isaiah
Shall your perversion be regarded like the potter’s clay (Heb. הָפְכְּכֶם) Your perversions. Do you know this, that it is like the potter’s clay? Just as the clay cannot say of its maker, “He did not make me,” so you cannot say that I do not understand your deeds.
Ibn Ezra on Isaiah
הפככם You are going from the truth.25A. V., Your turning of things upside down.
Rashi on Isaiah
Shall...like the potter’s clay, etc. This is an expression of a question, but there are questions to be answered in the affirmative.
