Verses 1–9
Nehemiah - Chapter 13
Infraction of the Law, Verses 1-9
The beginning of this chapter further indicates that the account of the dedication of the wall was an insertion in the account of the peopling of the refortified city of Jerusalem. The general subject, beginning with chapter 8, has been the revival of the people. They had gathered for the autumnal feasts and reading of the law. The opening words here, "On that day they read in the book of Moses in the audience of the people, etc." indicates that it was in the course of this reading they became aware of the prohibition now discovered. The law is recorded in De 23:3-4, where it is slightly more precise, reading, "even to their tenth generation shall they not enter into the congregation of the Lord forever." The indication is that the law was forever, that after the tenth generation those who embraced the law of Moses would evidently have been admitted.
The purpose of God’s prohibition against the Moabites and Ammonites stemmed from the effort of Balak, the king of Moab, to have the false prophet Balaam put a curse on Israel (Numbers ch. 22-24). Furthermore they had resisted the Israelites as they passed near the lands of their habitation, denying them food and water. When the Israelites, gathered to hear the law, heard this prohibition read, they responded by excluding all foreigners from their midst
There had been a very glaring violation of this prohibition in the person of Eliashib the high priest and Tobiah, the Ammonite troublemaker against Nehemiah. Some time previously there had been intermarriage between the family of the high priest and the foreigners, and Tobiah had acquired influential backers among the Jews (Nehemiah 13:28; Nehemiah 6:12-14). Eliashib had charge over the chambers built in the outside wall of the temple compound for the storage of tithes, votive offerings, materials used in temple service, etc. Probably some of these served as apartments for the ministering Levites, or the priests. Eliashib had emptied a large room of its intended use and made a commodious apartment for the Ammonite, Tobiah.
This had been going on during the time Nehemiah had gone back to Babylon to the service of Artaxerxes the Persian king. After an indeterminate period of time Nehemiah had secured permission from the king to go again to Jerusalem. On his arrival he discovered the old enemy of the wall-builders. Tobiah, being furnished an apartment even in the house of God. As mentioned earlier it is probable that Eliashib was succeeded by his son Joiada during the lifetime of Nehemiah, but Nehemiah held the old priest responsible for this "evil" of allowing Tobiah to live in the temple. Nehemiah’s righteous wrath was aroused. He went into the chambers and threw out all of Tobiah’s household goods and ordered the temple servants to cleanse and sanctify the quarters and to return the things there which rightfully belonged. That no protest is recorded indicates that those around recognized that Nehemiah was absolutely in the right in what he did (cf. 2 Corinthians 6:14-18).
