The Jewish New Year got a little sweeter at Manhattan’s Temple Emanu-El after the synagogue’s immediate past president made a $10 million donation.

The money from John Streicker brings his total gift to the Reform congregation to $25 million, and it is believed to be one of the largest donations ever to an American synagogue.

Harris Diamond, the synagogue president, announced the gift during the first night of Rosh Hashana services Monday at the Fifth Avenue temple.

Temple Emanu-El said it would use the cash for new initiatives to reach more people, including young Jewish professionals and families making decisions on their religious identity.

Streicker, a lawyer and real estate investment advisor, donated $15 million in 2016 to fund the temple’s Streicker Center, which holds educational and cultural programs.
