How is she clothed with "Oz v'Hadar"?
Malbim (Derech ha'Muskal): On the last day, she will be clothed with her ideas and good deeds.
What is the significance of Sechok on the last day?
Rashi: She will always be happy about the day of death - she will he honored with good repute.
Rashi (31, according to the Mashal): [Those who learn Torah] need not be sad from [concern for] Midas ha'Din, for they will be saved from it. Their entire lives, they are Sochek about Yom ha'Din. Tzechok 1 applies to one who need not fear - "va'Yischak l'Ra'ash Kidon" (Iyov 41:21).
Malbim (Derech ha'Muskal): She will rejoice, for the merit of the Rabim is due to her. She will reap the fruits of their deeds attributed to her, for she taught them to improve their ways - "u'Matzdkei ha'Rabim ka'Kochavim l'Olam va'Ed" (Daniel 12:3).
Rashi equates Tzechok and Sechok. (PF)
