Exodus 28:34-36

New Century Version

³⁴ All around the bottom of the outer robe there should be a gold bell and a pomegranate ball, a gold bell and a pomegranate ball. ³⁵ Aaron must wear this robe when he serves as priest. The ringing of the bells will be heard when he enters and leaves the Holy Place before the Lord so that Aaron will not die.

³⁶ “Make a strip of pure gold and carve these words on it as you would carve a seal: ‘Holy to the Lord.’
