It’s the eve of Rosh Hashana in a building erected in the 19th century by the Templers, a Lutheran sect from Germany, in what is now central Tel Aviv. A passerby peeking in through a window of the preserved structure will discover that it’s completely packed. And, unlike other places in the Sarona compound, this is not a place where they sell hamburgers or the latest fashions. Scattered on the tables are High Holy Day prayer books in Hebrew and in a Cyrillic alphabet. Young people, and also a few veteran immigrants, have crowded into the community center and house of prayer inaugurated in late August by Rabbi Yosef Hersonski. Welcome to the new synagogue for Russian speakers.
