Perach Mateh Aharon.

Resopnsa book, famous for its particularly beautiful title page, illustrated with elaborate images relating to priesthood, as the author was considered to be descendant of Aaron the high priest. The book was published after Rabbi Aharon Perachia Hacohen's death, by his son Azriel.

The name of the book translates as 'the flower of Aaron's rod', referring to an episode from the Torah, book of Numbers, where in order to determine which of the twelve tribes will become priests God commands that each of the tribes provide a rod; and only that of the tribe chosen to become priests will miraculously sprout overnight. Aaron provides his rod to represent the tribe of Levi, and 'it put forth buds, produced blossoms, and bore ripe almonds' (Numbers 17 8), as an evidence of the exclusive right to the priesthood of the tribe of Levi. Aaron then becomes the high priest.
