Thematic Bible: Intermarry with jews

After these things occurred, certain officials approached me and said "The people of Israel, the priests, and the descendants of Levi have not separated themselves from the people of the lands or from the detestable behavior of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites, because they and their sons have married foreign women. As a result, the holy people have mingled themselves among the nations of these lands. As a matter of fact, the senior officials and the rulers have been foremost in this sin."

Here is a list of priestly descendants who were found to have married foreign women. From Jeshua's descendants: Jozadak's son and his brothers Maaseiah, Eliezer, Jarib, and Gedaliah.
