Brit Kehunat Olam – First and Second Editions of Part I and First Edition of Part II – Lviv, 1796 and 1848
• Brit Kehunat Olam, Part I, kabbalistic homilies and allusions pertaining to the Jewish holidays, by R. Yitzchak Eizek Katz Rabbi of Korets and Ostroh. Lviv: Judith, wife of R. Tzvi Hirsh [Rosanes], [1796]. First edition. 
In his book Notzer Chessed, the Rebbe of Komarno, author of Heichal HaBerachah, writes of the holiness of R. Yitzchak Eizek Katz and his books: "The holy divine kabbalist, very astute… R. Yitzchak Eizek HaKohen, Rabbi of Korets and Ostroh, disciple of the great maggid R. Dov Ber of Mezeritch, author of Brit Kehunat Olam… Such a work has not appeared for several hundred years and he enlightened us with secrets of Torah and wisdom". R. Yitzchak Eizek was born ca. 1753-1758 and passed away in 1793. Great Chassidic masters cite his teachings with veneration. The Ahavat Yisrael of Vizhnitz would study this holy book daily, not ceasing even during the bombings of WWI.

• Brit Kehunat Olam, kabbalistic homilies and allusions pertaining to the Jewish holidays, Parts I-II, by R. Yitzchak Eizek Katz Rabbi of Korets and Ostroh. Lviv, 1848. First edition of Part II, printed from the author's manuscript.
The printing of Part II was delayed for many years, due to the prohibition to print kabbalistic books in Galicia (initiated by Galician maskilim). Upon the annulment of this prohibition in 1848, Part II of this book, which was still in manuscript form, was immediately brought to press. Part I, which by that time had sold out, was printed in the same volume.
