Exodus 28:37
Fasten to it a blue cord to mount it on the turban; it shall be on the front of the turban.
Berean Standard Bible
And thou shalt put it on a blue lace, that it may be upon the mitre; upon the forefront of the mitre it shall be.
You shall put it on a lace of blue, and it shall be on the sash. It shall be on the front of the sash.
