Friend,    With Purim right around the corner, Sefaria is busy preparing for the “Purim bump” — the increase in users who visit Sefaria to celebrate the holiday. Last year, more than 100,000 people visited the library or used the app to connect with the holiday or read along with Megillat Esther. This year we’re expecting even more.    To help with our text and tech preparations ahead of this busy time, a generous Jewish foundation is matching all gifts to the library up to $36,000.    Please give today to help us meet your learning needs!
