Ezra 10:5-6

So Ezra got up and made the priests, Levites, and all the people of Israel promise to do what was suggested; and they promised. Then Ezra left the Temple and went to the room of Jehohanan son of Eliashib. While Ezra was there, he did not eat or drink, because he was still sad about the unfaithfulness of the captives who had returned.
