'Be Holy' in the Bible

Now if the first fruits be holy, so is the mass: and if the root be holy, so are the branches.

A wife and a virgin hath different pursuits: the unmarried woman is anxious about the things of the Lord, that she may be holy both in body and spirit; but the married woman is anxious about the things of the world, how she shall please her husband.

as he hath elected us in him before the foundation of the world, that we should be holy and blameless before him in love:

that he might present it to himself a glorious church, not having blemish, nor wrinkle, nor any such things; but that it may be holy and unblameable.

He that is unjust, let him be unjust still; and he that is filthy, let him be filthy still; and he that is righteous, let him be righteous still; and he that is holy, let him be holy still.
