'Necklace' in the Bible

He made chains [like a necklace] in the inner sanctuary and put them on the tops of the pillars; and he made a hundred pomegranates and put them on the chains.

“You have ravished my heart and given me courage, my sister, my [promised] bride;You have ravished my heart and given me courage with a single glance of your eyes,With one jewel of your necklace.
