The Establishment Of The Temple Treasury, And The Chambers To Contain The Heave-offerings, Firstfruits and Tithes That Were Offered To YHWH, Their Restoration, And The Exclusion Of All Who Religiously Defiled Jerusalem (Nehemiah 12:44 to Nehemiah 13:14).
Equally of importance with the celebrations over the completion of the wall, were the arrangements made to ensure that Jerusalem continued to be the holy city, set apart to YHWH, purified from all that religiously defiled, and fulfilling its function as the YHWH's earthy dwellingplace, and as the store-city of all that specifically belonged to YHWH (that which had been set apart for Him and given to Him in accordance with the Law). To the mundane mind the building of the wall of Jerusalem had made it a defensible city suitable to be the capital of Judah, and thus an achievement in itself, but to the religious mind what the wall indicated was a new beginning of Jerusalem as ‘the holy city' which was the centre of true Yahwism.
This portion (Nehemiah 12:44 to Nehemiah 13:14) is distinguished by being fashioned on a clear chiastic pattern, as follows:
A Appointment of men over the treasure and store chambers (Nehemiah 12:44 a).
B The store chambers were for the treasures, heave-offerings, firstfruits and tithes (Nehemiah 12:44 b).
C All Judah rejoiced over the priests, and over the Levites who waited (before God) and gave them their portions as every day required (Nehemiah 12:44).
D In accordance with the Law of YHWH concerning the Moabites and Ammonites all who were religiously tainted were separated from Israel (Nehemiah 13:1-3).
E Eliashib who was the priest who was appointed over the chambers, provided a chamber for Tobiah the Ammonite, a chamber which had previously been used for the storage of those things which had been given to God (Nehemiah 13:4-5).
F All this happened when Nehemiah was away from Jerusalem, having returned to the king's court, probably at this stage stationed at Babylon (Nehemiah 13:6).
E Nehemiah learns what Eliashib had done in providing Tobiah with a chamber in the courts of the house of God (Nehemiah 13:7).
D Tobiah the Ammonite was cast out of the Temple chambers which were cleansed and restored to their proper use (Nehemiah 13:8-9).
C The portions of the Levites had not been given to them with the result that the house of God was forsaken by its servants who no longer waited before God (Nehemiah 13:10-11),
B All Judah brought the tithes to the treasuries (Nehemiah 13:12).
A Appointment of men over the treasuries (Nehemiah 13:13-14).
Note that in A men were appointed over the treasure and store chambers, and in the parallel men were appointed over the treasury. In B the store chambers were for various things including the tithes, and in the parallel all Judah brought tithes to the treasury. In C the portions were given to the priests and Levites as every day required, and in the parallel their portions were not given to the Levites. In D all who were religiously tainted, including the Ammonites, were separated from Israel, and in the parallel Tobiah the Ammonite was cast out of the Temple chambers which had to be cleansed. In E Eliashib provided a chamber for Tobiah, ad in the parallel Nehemiah learned of it. Centrally all this happened whilst Nehemiah was away from Jerusalem
