Ezra 10:5-6

So Ezra stood up and demanded that the leaders of the priests and the Levites and all the people of Israel swear that they would do as Shecaniah had said. And they all swore a solemn oath. Then Ezra left the front of the Temple of God and went to the room of Jehohanan son of Eliashib. He spent the night there without eating or drinking anything. He was still in mourning because of the unfaithfulness of the returned exiles.
