'Holy to the Lord' in the Bible

“You are to make a pure gold medallion and engrave it, like the engraving of a seal:HOLY TO THE LORD.

“Once a year Aaron is to perform the purification rite on the horns of the altar. Throughout your generations he is to perform the purification rite for it once a year, with the blood of the sin offering for atonement. The altar is especially holy to the Lord.”

They also made a medallion, the holy diadem, out of pure gold and wrote on it an inscription like the engraving on a seal:HOLY TO THE LORD.
