اَلْخُرُوجُ 28:28

وَيَرْبُطُونَ ٱلصُّدْرَةَ بِحَلْقَتَيْهَا إِلَى حَلْقَتَيِ ٱلرِّدَاءِ بِخَيْطٍ مِنْ أَسْمَانْجُونِيٍّ لِتَكُونَ عَلَى زُنَّارِ ٱلرِّدَاءِ، وَلَا تُنْزَعُ ٱلصُّدْرَةُ عَنِ ٱلرِّدَاءِ.

And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a lace of blue, that it may be above the curious girdle of the ephod, and that the breastplate be not loosed from the ephod.
