Chagall later told a friend that Israel gave him "the most vivid impression he had ever received". Wullschlager notes, however, that whereas Delacroix and Matisse had found inspiration in the exoticism of North Africa, he as a Jew in Israel had different perspective. "What he was really searching for there was not external stimulus but an inner authorization from the land of his ancestors, to plunge into his work on the Bible illustrations". Chagall stated that "In the East I found the Bible and part of my own being."
