'Set apart' in the Bible

In you have they uncovered their fathers' nakedness: in you have they violated her that was set apart for her impurity.

And they shall set apart men of continual employment, passing through the land to bury with the travelers those that remain upon the face of the land, to cleanse it: after the end of seven months shall they make a search.

All the district shall be five and twenty thousand by five and twenty thousand: you shall set apart the holy district as a square, with the possession of the city.
