EPHRAIM BEN JOSEPH OF CHELM (JAMBROWER):
Polish liturgist; born at Chelm, Poland, at the end of the sixteenth century; died at Wreshna, Poland, about 1650. His father, rabbi at Jambrower, Poland, entrusted his education to David ben Jacob of Szczebrszyn. After residing for some years at Cracow, Ephraim was called as rabbi to Wreshna. He wrote "Ba-Kosharot," in two parts, containing twenty-two liturgical poems, some of which are accompanied by a commentary and by halakic decisions (Cracow, 1607).
