'Be Holy' in the Bible

Then said he unto me, "The chambers toward the north and the south which stand before the back building: those be holy habitations, wherein the priests that do service before the LORD must eat the most holy offerings. And there must they lay the most holy offerings: meat offerings, sin offerings and the trespass offerings, for it is a holy place.

When the priests come therein, they shall not go out in to the fore court: but, seeing they be holy, they shall leave their clothes of their ministration, and put on other garments, when they have any thing to do with the people."

When ye divide the land by the lot, ye shall put aside one part for the LORD, to be holy from other lands: namely twenty five thousand measuring rods long, and ten thousand broad. This shall be holy, as wide as it is round about.
