'Separated' in the Bible

And I said unto the nobles, and to the rulers, and to the rest of the people, The work is great and large, and we are separated upon the wall, one far from another.

And the seed of Israel separated themselves from all strangers, and stood and confessed their sins, and the iniquities of their fathers.

And the rest of the people, the priests, the Levites, the porters, the singers, the Nethinims, and all they that had separated themselves from the people of the lands unto the law of God, their wives, their sons, and their daughters, every one having knowledge, and having understanding;

Now it came to pass, when they had heard the law, that they separated from Israel all the mixed multitude.
