Rabbi Moses David Valle (circa 1697 – December 17, 1776) was a Jewish biblical commentator, physician, scholar, and Kabbalist from Italy.

At the age of 25, he wrote a treatise in Italian on Christianity titled "I Sette Giorni della Verit" and authored numerous writings on the Bible, comprising around 15,000 pages, some of which are in manuscript form.

Therefore, one should not replace the wisdom of our ancestors with anything, but only make a slight change in the quantity of medicine, not in its quality, because the nature and temperament of people have weakened, and they cannot endure the abundance of remedies as in ancient times.

Rabbi Moses David Valle passed away on the 7th of Tevet, 5477 (1776), and was buried in the cemetery on Via Domenico Campagnola 24 in Padua.

His tombstone bears the inscription: Here lies the esteemed sage, the divine physician, the Kabbalist, the holy Rabbi Moses David Valle, may his memory be blessed, who passed away on Tuesday, the 7th of the month of Tevet, in the year 5477.According to his writings, he had a son with his wife and named him Samuel Chaim after his father.
