'Sojourners' in the Bible

seven days leaven is not found in your houses, for any one eating anything fermented -- that person hath been cut off from the company of Israel, among the sojourners or among the natives of the land;

'And a sojourner thou dost not oppress, nor crush him, for sojourners ye have been in the land of Egypt.

And a sojourner thou dost not oppress, and ye -- ye have known the soul of the sojourner, for sojourners ye have been in the land of Egypt.
