Ezra 2:61; Ezra 9:2; Ezra 9:12

61 Of the sons of the priests: the sons of Habaiah, the sons of Hakkoz, the sons of Barzillai, who took a wife from the daughters of Barzillai the Gileadite, and he was called by their name.

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."

12 'So now do not give your daughters to their sons nor take their daughters to your sons, and never seek their peace or their prosperity, that you may be strong and eat the good things of the land and leave it as an inheritance to your sons forever .'
