'Themselves' in the Bible

For the priests and the Levites had purified themselves together; all of them were pure. Then they slaughtered the Passover lamb for all the exiles, both for their brothers the priests and for themselves.

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.

For they have taken some of their daughters as wives for themselves and for their sons, so that the holy race has intermingled with the peoples of the lands; indeed, the hands of the princes and the rulers have been foremost in this unfaithfulness.”
