Ezra 9:2

2 "For they have taken some of their daughters as wives for themselves and for their sons, so that the holy race has intermingled with the peoples of the lands; indeed, the hands of the princes and the rulers have been foremost in this unfaithfulness."

Ezra 9:4

4 Then everyone who trembled at the words of the God of Israel on account of the unfaithfulness of the exiles gathered to me, and I sat appalled until the evening offering.

Ezra 10:6

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