Ezra 7:25

7:25 “Now you, Ezra, in keeping with the wisdom of your God which you possess, appoint judges and court officials who can arbitrate cases on behalf of all the people who are in Trans-Euphrates who know the laws of your God. Those who do not know this law should be taught.

Ezra 9:2

9:2 Indeed, they have taken some of their daughters as wives for themselves and for their sons, so that the holy race has become intermingled with the local residents. Worse still, the leaders and the officials have been at the forefront of all of this!”
