'Separated' in the Bible

The sons of Israel who returned from exile and all those who had separated themselves from the impurity of the nations of the land to join them, to seek the Lord God of Israel, ate the Passover.

Now when these things had been completed, the princes approached 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, those of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians and the Amorites.
