What does Ezra 9:2 mean?

Some of our own people, including leaders and officials, have married into the local families who don't follow our ways. It's not just a few—it's a lot of them. Even the ones who should be setting the example have led the way in this. Ezra 9:2 - Modern Text Bible

(Ezra is upset because many Israelites, including those in positions of authority, have married people from surrounding groups who don't share their faith or values. This is seen as a serious problem because it threatens their identity and commitment to God.)
