Note: the chronology of this section is difficult but the purpose of bringing these events together is a lot clearer. Israel had agreed to separate themselves and support the work of the Levites as part of their commitment to the House of God, but in Nehemiah’s absence standards had fallen away under Eliashib the High Priest. When Nehemiah returns he cleanses the House of God and re-institutes the tithing for the Levites.
A. 11:44 And at that time were some appointed over the chambers for the treasures, for the offerings, for the firstfruits, and for the tithes, to gather into them out of the fields of the cities the portions of the law for the priests and Levites: for Judah rejoiced for the priests and for the Levites that waited. 45 And both the singers and the porters kept the ward of their God, and the ward of the purification, according to the commandment of David, and of Solomon his son. 46 For in the days of David and Asaph of old there were chief of the singers, and songs of praise and thanksgiving unto God.
B. 47 And all Israel in the days of Zerubbabel, and in the days of Nehemiah, gave the portions of the singers and the porters, every day his portion: and they sanctified holy things unto the Levites; and the Levites sanctified them unto the children of Aaron.
C. 13:1 On that day they read in the book of Moses in the audience of the people; and therein was found written, that the Ammonite and the Moabite should not come into the congregation of God for ever; 2 Because they met not the children of Israel with bread and with water, but hired Balaam against them, that he should curse them: howbeit our God turned the curse into a blessing. 3 Now it came to pass, when they had heard the law, that they separated from Israel all the mixed multitude.
D. 4 And before this, Eliashib the priest, having the oversight of the chamber of the house of our God, was allied unto Tobiah: 5 And he had prepared for him a great chamber, where aforetime they laid the meat offerings, the frankincense, and the vessels, and the tithes of the corn, the new wine, and the oil, which was commanded to be given to the Levites, and the singers, and the porters; and the offerings of the priests.
E. 6 But in all this time was not I at Jerusalem: for in the two and thirtieth year of Artaxerxes king of Babylon came I unto the king, and after certain days obtained I leave of the king:
D’. 7 And I came to Jerusalem, and understood of the evil that Eliashib did for Tobiah, in preparing him a chamber in the courts of the house of God.
C’. 8 And it grieved me sore: therefore I cast forth all the household stuff of Tobiah (an Ammonite) out of the chamber. 9 Then I commanded, and they cleansed the chambers: and thither brought I again the vessels of the house of God, with the meat offering and the frankincense.
B’. 10 And I perceived that the portions of the Levites had not been given them: for the Levites and the singers, that did the work, were fled every one to his field. 11 Then contended I with the rulers, and said, Why is the house of God forsaken? And I gathered them together, and set them in their place.
A’. 12 Then brought all Judah the tithe of the corn and the new wine and the oil unto the treasuries. 13 And I made treasurers over the treasuries, Shelemiah the priest, and Zadok the scribe, and of the Levites, Pedaiah: and next to them was Hanan the son of Zaccur, the son of Mattaniah: for they were counted faithful, and their office was to distribute unto their brethren.
