'Separated' in the Bible

The children of Israel who had come again out of the captivity, and all such as had separated themselves to them from the filthiness of the nations of the land, to seek Yahweh, the God of Israel, ate,

Now when these things were done, the princes drew near to me, saying, "The people of Israel, and the priests and the Levites, have not separated themselves from the peoples of the lands, [doing] according to their abominations, even of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites.

and that whoever didn't come within three days, according to the counsel of the princes and the elders, all his substance should be forfeited, and himself separated from the assembly of the captivity.
