'Be Holy' in the Bible

In that day there will be written on the little bells on the horses, “HOLY TO The Lord.” And the cooking pots in the Lord’s house will be [holy to the Lord] like the bowls before the altar.

Yea, every pot in Jerusalem and in Judah shall be holy unto Jehovah of hosts; and all they that sacrifice shall come and take of them, and boil therein: and in that day there shall be no more a Canaanite in the house of Jehovah of hosts.
