'Themselves' in the Bible

because the priests and descendants of Levi had purified themselves together all of them were pure and they killed the Passover lamb for every former exile, for their relatives the priests, and for themselves.

So the Israelis who had returned from captivity ate the Passover with all who had consecrated themselves from the uncleanness of the nations of the land in order to seek the LORD God of Israel.

After these things occurred, certain officials approached me and said "The people of Israel, the priests, and the descendants of Levi have not separated themselves from the people of the lands or from the detestable behavior of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites,

because they and their sons have married foreign women. As a result, the holy people have mingled themselves among the nations of these lands. As a matter of fact, the senior officials and the rulers have been foremost in this sin."

So those who had returned from exile did this. Ezra the priest and leaders of certain ancestral groups listed by name devoted themselves to examine the situation on the first day of the tenth month.
