Exodus 28:28-30

Holman Christian Standard Bible

²⁸ The craftsmen are to tie the breastpiece from its rings to the rings of the ephod with a cord of blue yarn, so that the breastpiece is above the ephod’s waistband and does not come loose from the ephod.

²⁹ “Whenever he enters the sanctuary, Aaron is to carry the names of Israel’s sons over his heart on the breastpiece for decisions, as a continual reminder before the Lord. ³⁰ Place the Urim and Thummim^(A) in the breastpiece for decisions, so that they will also be over Aaron’s heart whenever he comes before the Lord. Aaron will continually carry the means of decisions for the Israelites over his heart before the Lord.
