'Holy to the Lord' in the Bible

“Israel was holy to the Lord,The first of His harvest.All who ate of it became guilty;Evil came upon them,” declares the Lord.’”

And the whole valley of the dead bodies and of the ashes, and all the fields as far as the brook Kidron, to the corner of the Horse Gate toward the east, shall be holy to the Lord; it will not be plucked up or overthrown anymore forever.”
