'Diadem' in the Bible

And thou shalt put the turban upon his head, and fasten the holy diadem to the turban,

And they made the thin plate, the holy diadem, of pure gold, and wrote on it with the writing of the engravings of a seal, Holiness to Jehovah!

and he put the turban upon his head; and upon the turban, on the front of it, he put the golden plate, the holy diadem; as Jehovah had commanded Moses.

In that day will Jehovah of hosts be for a crown of glory, and for a diadem of beauty, unto the remnant of his people;

And thou shalt be a crown of beauty in the hand of Jehovah, and a royal diadem in the hand of thy God.
