וַיַּ֤רְא מֹשֶׁה֙ אֶת־הָעָ֔ם כִּ֥י פָרֻ֖עַ ה֑וּא כִּֽי־פְרָעֹ֣ה אַהֲרֹ֔ן לְשִׁמְצָ֖ה בְּקָמֵיהֶֽם׃
Nakita ni Moises na ang bayan ay nalantad, sapagkat inilantad sila ni Aaron sa kahihiyan sa harap ng mga tumatayo laban sa kanila.
Rashi
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”.
Ramban
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.
Rashbam
כי פרוע הוא, had ceased to observe the commandments. We encounter this expression in this sense in Proverbs 1,25 ותפרעו כל עצתי, “You have spurned all My advice.” It appears again in Proverbs 4,15 in a similar sense.
