Ezra 10:1

Then Ezra arose from before the house of God and went into the chamber of Jehohanan the son of Eliashib. He went there, but he did not eat bread nor drink water, for he was mourning over the unfaithfulness of the exiles.

Now it happened that when I heard these words, I sat down and wept and mourned for days; and I was fasting and praying before the God of heaven.

let Your ear now be attentive and Your eyes open to hear the prayer of Your slave which I am praying before You today, day and night, on behalf of the sons of Israel Your slaves, confessing the sins of the sons of Israel which we have sinned against You; I and my father’s house have sinned.
