'Separated' in the Bible

I said to the nobles, the officials and the rest of the people, “The work is great and extensive, and we are separated on the wall, far from one another.

The descendants of Israel (Jacob) separated themselves from all foreigners, and stood and confessed their sins and the wrongdoings of their fathers.

Now the rest of the people—the priests, the Levites, the gatekeepers, the singers, the temple servants, and all those who had separated themselves from the peoples of the lands to the Law of God, their wives, their sons, their daughters, all those who had knowledge and understanding—

When the Jews heard the law, they separated from Israel all who were of foreign descent.
