Musar for Genesis 45:22
לְכֻלָּ֥ם נָתַ֛ן לָאִ֖ישׁ חֲלִפ֣וֹת שְׂמָלֹ֑ת וּלְבִנְיָמִ֤ן נָתַן֙ שְׁלֹ֣שׁ מֵא֣וֹת כֶּ֔סֶף וְחָמֵ֖שׁ חֲלִפֹ֥ת שְׂמָלֹֽת׃
To all of them he gave each man changes of raiment; but to Benjamin he gave three hundred shekels of silver, and five changes of raiment.
Shenei Luchot HaBerit
In his capacity as provider for the land of Egypt, Joseph acted as a forerunner of those idyllic times. He not only provided food for all his father's family, but also clothes to wear as per Genesis 45, 22. The reason the Torah describes that clothing as חליפות, something subject to exchange, is that in the future these garments will indeed be exchanged for the type of garments woven of light that Adam and Eve used to wear prior to their sin.
