Jacob Wright (2004) has carried out similar work on Nehemiah. According to his study the original "Nehemiah memoir" was an account of the rebuilding of the city walls. Successive layers were then added to this, turning the building report into an account of Judah's restoration and depicting Nehemiah as a Persian governor who reforms the community of Israel. Finally, after Ezra had come into existence through the combination of Ezra 1–6 with Ezra 7–10, the accounts of the repopulation and dedication of the city and the friction between Temple and torah were added to produce the final book of Nehemiah. Furthermore, in Wright's article his main issue is of course the literature of the text. The argument comes when Nehemiah notices that the Judeans were marrying people outside of their lands (exogamy) whose children spoke the same language. Although this came during the 52 days of the construction of the wall, we are not sure how he noticed the issue. The non clarity in the text according to Wright is as if Ezra already outlawed Judean men not to marry any one outside of their land, then why is Nehemiah noticing it thirteen years later. According to Wright the issue in Ezra 9–10 is in the verse 24, where it says that half of the children spoke another language and did not know the language of Judah. Even though the issue in the text says it is not worried about the survival of the Judean language Nehemiah cannot endorse the exogamous marriage. After punishing the men, that is when he makes them take the oath however Wright's argument is if Nehemiah actually composed that text, in which he did not know a passage in Deuteronomy, then why does he compose an oath that does not match the issue that was in the previous verse.
