Born in Prague, Elazar was a student of Yechezkel Landau, the Noda BiYehuda. He then served as rabbi in Goitein, Moravia for four years, after which he returned to Prague and served as a judge in the rabbinical court of R. Landau. He was a fierce opponent of the Sabbateans and suffered greatly from their retaliations. He wrote several works, among them his responsa, entitled "Teshuvah MeAhava."
