Ezra 10:4-6

American Standard Version

⁴ Arise; for the matter belongeth unto thee, and we are with thee: be of good courage, and do it.

⁵ Then arose Ezra, and made the chiefs of the priests, the Levites, and all Israel, to swear that they would do according to this word. So they sware. ⁶ Then Ezra rose up from before the house of God, and went into the chamber of Jehohanan the son of Eliashib: and when he came thither, he did eat no bread, nor drink water; for he mourned because of the trespass of them of the captivity.
