Wentworth Arthur Matthew founded the Commandment Keepers Congregation in Harlem in 1919. Matthew was influenced by the non-black Jews he met as well as by Marcus Garvey and the Universal Negro Improvement Association and African Communities League. Garvey used the Biblical Jews in exile as a metaphor for black people in North America. One of the accomplishments of Garvey's movement was to strengthen the connection between black Americans and Africa, Ethiopia in particular. When Matthew later learned about the Beta Israel—Ethiopian Jews—he identified with them.
