This pamphlet contains a discourse delivered by Isaac Leeser on the seventeenth anniversary of the dedication of Mikveh Israel Synagogue in Philadelphia, Pennsylvania. The discourse addresses the question of Israel's continued status as God's chosen people, despite their dispersion and oppression. Leeser argues against the notion that Israel's rejection is a consequence of their failure to accept a new messiah, emphasizing the sufficiency and enduring validity of the Mosaic law and God's unchanging covenant with Israel. The pamphlet includes an exchange of letters between Abraham Hart, President of the congregation, and Leeser regarding the publication of the sermon.
