'Themselves' in the Bible

The priests and the Levites had purified themselves, every last one, and they all were ceremonially pure. They sacrificed the Passover lamb for all the exiles, for their colleagues the priests, and for themselves.

The Israelites who were returning from the exile ate it, along with all those who had joined them in separating themselves from the uncleanness of the nations of the land to seek the Lord God of Israel.

Now when these things had been completed, the leaders approached me and said, "The people of Israel, the priests, and the Levites have not separated themselves from the local residents who practice detestable things similar to those of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites.

Indeed, they have taken some of their daughters as wives for themselves and for their sons, so that the holy race has become intermingled with the local residents. Worse still, the leaders and the officials have been at the forefront of all of this!"
