'Be Holy' in the Bible

But the Lord of armies is lifted up as judge, and the Holy God is seen to be holy in righteousness.

But let the Lord of armies be holy to you, and go in fear of him, giving honour to him.

And her merchandise and her hire shall be holy to Jehovah: it shall not be treasured nor laid up; for her merchandise shall be for them that dwell before Jehovah, to eat and be sufficed, and for excellent clothing.
