Exodus 36:29

²⁷And they made two golden rings, and put them on both the shoulders of the ephod under it, in front by the coupling above the connection of the ephod.

²⁸And he fastened the oracle by the rings that were on it to the rings of the ephod, which were fastened with a string of blue, joined together with the woven work of the ephod; that the oracle should not be loosed from the ephod, as the Lord commanded Moses.

— Exodus 36:29 —

³⁰And the opening of the tunic in the midst woven closely together, the opening having a fringe round about, that it might not be rent.

³¹And they made on the border of the tunic below pomegranates as of a flowering pomegranate tree, of blue, and purple, and spun scarlet, and fine linen twined.
