9861.“这胸牌要四方的、叠为两层”表公义和完美之物。这从“四方”的含义清楚可知，“四方”是指公义之物（参看9717节）。之所以也表示完美之物，是因为胸牌是两层的，两层的意味着良善的各个方面和真理的各个方面。右边的意味着真理所源于的良善，左边的意味着源于良善的真理（9495，9604e，9736节），因而也意味着这二者完美地结合在一起。也正因如此，“二”表示结合（8423节），也表示它们的每一个方面（9166节），以及它们的完整性（9103节）。

9861. Foursquare it shall be, doubled. That this signifies what is righteous and perfect, is evident from the signification of "foursquare," as being what is righteous (see n. 9717). That it also means what is perfect, is because it was doubled, and that which is doubled involves all things of good and all things of truth. That which is on the right side involves the good from which is truth, and that which is on the left side involves the truth which is from good (n. 9495, 9604, 9736), thus the perfect conjunction of both is involved. It is also from this that "two" signifies conjunction (n. 8423), and also each and all things (n. 9166), as likewise what is full (n. 9103).

9861. 'It shall be square when doubled' means that which is righteous and perfect. This is clear from the meaning of 'square' as that which is righteous, dealt with in 9717. The reason why that which is also perfect is meant is that the breastplate was doubled, and that which is doubled implies all aspects of good and all aspects of truth. What is on the right side implies the good from which truth springs, and what is on the left implies the truth springing from good, 9495, 9604 (end), 9736, thus also the two perfectly joined to each other. This accounts furthermore for the meaning of 'two' as things joined together, 8423, also every single aspect of them, 9166, and their completeness as well, 9103.

9861. `Quadratum erit duplicatum': quod significet justum et perfectum, constat ex significatione `quadrati' quod sit justum, de qua n. 9717; quod etiam sit perfectum, est quia erat duplicatum, et {1}duplicatum involvit omnia boni et omnia veri; quod a parte dextra involvit bonum ex quo verum, et quod a sinistra verum ex bono, n. (a)9495, 9604 fin., 9736, ita quoque perfectam conjunctionem utriusque; inde quoque est (x)quod duo significent conjunctionem, n. 8423, et quoque omnia et singula, n. 9166, ut et plenum, n. 9103. @1 duplicatio$
