And after these things were accomplished, the princes came to me, saying: The people of Israel, and the priests and Levites have not separated themselves from the people of the lands, and from their abominations, namely, of the Chanaanites, and the Hethites, and the Pherezites, and the Jebusites, and the Ammonites, and the Moabites, and the Egyptians, and the Amorrhites.
Ezra 9:1 And after these things were accomplished, the princes came to me, saying: The people of Israel, and the priests and Levites have not separated themselves from the people of the lands, and from their abominations, namely, of the Chanaanites, and the Hethites, and the Pherezites, and the Jebusites, and the Ammonites, and the Moabites, and the Egyptians, and the Amorrhites.
Ezra 9:2 For they have taken of their daughters for themselves and for their sons, and they have mingled the holy seed with the people of the lands. And the hand of the princes and magistrates hath been first in this transgression.
Ezra 9:3 And when I had heard this word, I rent my mantle and my coat, and plucked off the hairs of my head and my beard, and I sat down mourning.
The verse centers on "after", "things", "accomplished", "princes", "came", "saying", "people", and "israel". It is saying that the verse draws attention to "after" and "things", so its meaning should be read from those terms before moving to application.
The next verse adds "For they have taken of their daughters...", so "after" and "things" should be read forward into that movement. In Ezra context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "after" and "things" with trust shaped by these words, not by a vague optimism outside the passage.
