פירוש על שמות 32:25

פרע means UNCOVERED — its (the people’s) shame and disgrace were revealed; the word has the same meaning as in (Numbers 5:18) “[and the priest shall uncover (ופרע) the woman’s head”.

AND MOSES SAW THAT THE PEOPLE WERE ‘PHARUA’ (BROKEN LOOSE). The meaning of this is that although Aaron defended himself and said that he was not at fault with them, yet Moses knew in his heart that the people were broken loose — For they are a nation void of counsel, and there is no understanding in them.³⁶⁸Deuteronomy 32:28. It is similar to the expression, ‘vatiphr’u’ (and ye have set at nought) all my counsel,³⁶⁹Proverbs 1:25. and similar also to the verse, for ‘hiphria’ (he had cast away restraint) in Judah, and acted treacherously against the Eternal.³⁷⁰II Chronicles 28:19. [Thus the verse is stating that Moses saw] that Aaron had let the people loose, and left them without any counsel and instruction, so that they became like sheep scattered upon the mountains³⁷¹See I Kings 22:17. without counsellor and guide. Scripture stated this [especially] because they had thought that the calf would be their guide, but in fact they appeared as if they had no counsel, not knowing the way wherein they must walk, and the deeds they must do,³⁷²Above, 18:20. for some of them intended it for the good, according to their way of thinking, and others intended it for real evil [i.e., outright idolatry], and thus each one went his own way.

כי פרוע הוא, they are totally corrupt, committing their sins in public without shame. The public deeds reveal their deep-seated corruption.
