כִּ֣י אִם־הַחֲרֵ֣שׁ תַּחֲרִישִׁי֮ בָּעֵ֣ת הַזֹּאת֒ רֶ֣וַח וְהַצָּלָ֞ה יַעֲמ֤וֹד לַיְּהוּדִים֙ מִמָּק֣וֹם אַחֵ֔ר וְאַ֥תְּ וּבֵית־אָבִ֖יךְ תֹּאבֵ֑דוּ וּמִ֣י יוֹדֵ֔עַ אִם־לְעֵ֣ת כָּזֹ֔את הִגַּ֖עַתְּ לַמַּלְכֽוּת׃
이 때에 네가 만일 잠잠하여 말이 없으면 유다인은 다른 데로 말미암아 놓임과 구원을 얻으려니와 너와 네 아비 집은 멸망하리라 네가 왕후의 위를 얻은 것이 이 때를 위함이 아닌지 누가 아느냐
Shelom Esther
Some say that its content is similar to that of a Torah scroll, and that is enough. But where is it hinted? Some say where it is written (Esther 4:14), "from another place (makom)." As "Makom is nothing other than the Holy One, blessed be He. And others say it is in (Esther 5:4), "yavo hamelekh veHaman hayom, (spelling out the name of God as an anagram). And [still] others say it is in (Esther 7:8), "oupnei Haman chafu. And it is written that way (the anagram is missing the last letter), since the wicked reverse the trait of mercy (alluded to by this name of God) into (strict) justice. This is like the matter of that which they, may their memory be blessed, said on the verse (Exodus 9:3), "Behold, the hand of the Lord is." And that is why it is written by hinting to it; since the Holy One, blessed be He does not attach His Name to evil.
Rashi
your strength will be weak indeed on the day of your punishment, as it is written (Esther 4:14): “For if you remain silent, etc.”
