What happens when the system that supports worship breaks down? People get forced to abandon their calling.
This verse reveals a critical failure: the 'portions of the Levites had not been given them.' This wasn't just an oversight; it was a fundamental neglect that had severe consequences.
The Root Cause
Commentaries suggest this failure stemmed from corrupt leadership and/or a disengaged people. Either the high priest and officials were misusing the tithes and offerings (like diverting them for personal gain or entertaining foreigners, as hinted at in other parts of Nehemiah), or the people, disheartened by such corruption or simply out of selfishness, withheld their contributions.
A Domino Effect
Regardless of the exact cause, the result was the same: the Levites and singers, the spiritual workforce, were left without the means to live and serve. They were forced to leave the Temple and return to their ancestral lands to farm, abandoning their sacred duties. This left the 'house of God forsaken,' as Nehemiah notes in the next verse.
