Ezra 9:1-2

1Now when these things were completed, the princes came to me, saying, The people of Israel, and the priests and the Levites, have not separated themselves from the peoples of the lands, according to their abominations, [even] of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites;

2for they have taken of their daughters for themselves and for their sons, and have mingled the holy seed with the peoples of the lands; and the hand of the princes and rulers has been chief in this unfaithfulness.
