Ezra 10:6 (KJV)

Arise; for this matter belongeth unto thee: we also will be with thee: be of good courage, and do it.

Then arose Ezra, and made the chief priests, the Levites, and all Israel, to swear that they should do according to this word. And they sware.

Then Ezra rose up from before the house of God, and went into the chamber of Johanan the son of Eliashib: and when he came thither, he did eat no bread, nor drink water: for he mourned because of the transgression of them that had been carried away.

And they made proclamation throughout Judah and Jerusalem unto all the children of the captivity, that they should gather themselves together unto Jerusalem;

And that whosoever would not come within three days, according to the counsel of the princes and the elders, all his substance should be forfeited, and himself separated from the congregation of those that had been carried away.
