Two of his declarations are famous, and still considered accurate: Concerning the verse, "Miriam and Aaron spoke out against Moses because of the Cushite woman he had married, He married a Cushite woman" – he clarified that "she was of the seed of Dan, who reside in the mountains of Cush"; he also ruled that the location of the Holy of Holies is beneath the Dome of the Rock, on the Temple Mount.
Hacham David Ben Zimra passed away on 21 Heshvan 5333 (1573) and lies buried in the ancient cemetery of Safed.
