Speak to the entire congregation of the children of Israel, and say to them,

You shall be holy, for I, the Lord, your God, am holy.

“The mitzvot ‘bein adam l’chaveiro‘, the commandments of proper conduct between man and his fellow man… also express holiness.

So holiness is not only expressed by separation from the forbidden foods and from forbidden sexual relations. Holiness is also [reflected] by a person’s personal conduct; how one behaves with others, which in turn is a reflection of who a person really is…

The commandments that apply in the behaviour of man and his fellows… are [also] included in the main commandments of holiness…precisely because the whole concept of holiness as defined by separation really means setting a higher standard than the generally accepted norm.”
