Rabbeinu Bahya
וישמע העם את הדבר הרע הזה, “when the people heard this bad tiding, etc.” It appears to me that the Israelites imposed upon themselves various kinds of afflictions, corresponding to the sin they had committed. Whereas previously they had worn crowns on their heads, reflecting their joy of being alive, now when they heard that the Shechinah had removed itself from their midst they responded by foregoing their previous joy in being alive. This the Torah describes in stages; 1) ויתאבלו, “they went into mourning;” 2) לא שתו, “they did not put on their jewelry.” The prophet Hoseah 2,5 describes the removal of jewelry as equivalent to being stripped naked of one’s garments when he says פן אפשיטנה ערומה והצגתיה כיום הולדה, “lest I strip her naked and display her as on the day she was born.” What he meant was that G’d threatened to deprive the Jewish people of the glory of the presence of His Shechinah. The Israelites had been in the habit of using this presence just like other people use their clothing to cover their nakedness to give them dignity. The Israelites would remain as they had been before G’d gave them the Torah, i.e. “naked.” Targum Yonatan understands the words of the prophet similarly when he wrote: דלמא אסליק שכינתי מנה ואעדי יקרה ואשוינה רטישא כזמני קדמאי עד לא אתקריבת לפולחני, “lest I remove My presence from them and My precious jewelry, and I will make them forsaken like before I brought them close to My service (the giving of the Torah).”
Rashi
הוסדה means [FROM THE DAY] WHEN IT WAS FOUNDED (נתיסדה). Every word (verb) the first root-letter of which is י, as יסד and ילד and ידע and יסר, when it is used in the Hithpael sense (Rashi means our Niphal which often is the reflexive of the Kal), a ו replaces this י; e. g., הוסדה here, from יסד; (Hosea 2:5) “her being born (הִוָלְדָּהּ)”; (Esther 2:22) “and it was known (ויודע)”; (Genesis 66:20) “and there was born (ויולד) to Joseph”; (Proverbs 29:19) A servant will not be corrected (יוסר) by words”.
