This article deals with Nehemiah 8:13-18, an episode describing the celebration of Sukkot's Festival after the reading of the Law by Ezra. It shows that those verses have been redacted by one of the last redactors of Ezra-Nehemiah. Sophisticated exegetical techniques have been used in order to present a story compatible with all legislative texts about Sukkot (Lev. 23:34-36; Lev. 23:39-43; Num. 29:12-39; Deut. 16:13-15 and Deut. 31:9-13). Furthermore, the redactor of Neh. 8:13-18 innovates introducing a daily lecture of the Law during Sukkot (Neh. 8:18). Ezra 3:4 has probably been written by the same hand.
