Manuscript by Rabbi Avraham Ben HaGra

Manuscript by Rabbi Avraham Ben HaGra
Handwritten manuscript leaf by Rabbi Avraham Ben HaGra, containing commentaries on verses from the Books of Kings. [Post 1798].
An inscription handwritten by his son Rabbi Ya'akov Moshe Slonim appears on the margins: "I printed this writing" (and indeed the texts appear in prints of Vilna and Horodna in 1820).
The Gaon Rabbi Avraham of Vilna (1766-1809) was the youngest and most beloved son of Rabeinu Eliyahu of Vilna, a brilliant genius in the Seen and Unseen, son-in-law of Rabbi Noah Mindis, of the Vilna geniuses (author of "Nifla'ot Hadashot" and "Papera'ot LaChochma"). It is said that he did not remove his hand from his father's hand all his life and heard from him many of the secrets of the Torah.
When his father passed away he headed the "HaGra Kloyz" in Vilna. He published his father's books and composed extensive introductions to HaGra's books. He added many commentaries to HaGra's books in the name of "Be'er Avraham" ("Aderet Eliyahu," etc.). He composed books about all sections of the Torah, commentaries on the Bible and the Book of Psalms, Tikunei Zohar and Legends of the Sages, and more. He refers to numerous writings of his father, the Vilna Gaon, in his books. His son was Rabbi Moshe Landau of Slonim-Jerusalem, who followed in his path and published books by HaGra and by his father, Rabbi Avraham.
