C. F. Keil and Franz Delitzsch on Nehemiah 5:17

Neh 5:17

But this was not all; for Nehemiah had also fed a considerable number of persons at his table, at his own expense. “And the Jews, both one hundred and fifty rulers, and the men who came to us from the nations round about us, were at my table,” i.e., were my guests. The hundred and fifty rulers, comp. Neh 2:16, were the heads of the different houses of Judah collectively. These were always guests at Nehemiah’s table, as were also such Jews as dwelt among the surrounding nations, when they came to Jerusalem.
