Exodus 39:19-21

International Standard Version

¹⁹ They made two gold rings and attached them to the two edges of the breast piece, on the side of it which is toward the inner side of the ephod. ²⁰ They made two gold rings and attached them in front, on the lower part of the two shoulder pieces of the ephod, close to the place where it’s joined, above the skillfully woven band of the ephod. ²¹ They tied the breast piece by its rings to the rings of the ephod with a blue cord so it would rest on the skillfully woven band of the ephod and so the breast piece would not come loose from the ephod.
