You say this, but perhaps it speaks of one" — It is not written "Whom elohim shall incriminate ("yarshiyen," with a vav, [which would signify two]), but "yarshian," (without the vav, which signifies one), so that, (all together) Scripture speaks of two. And "there is no equally balanced beth-din," wherefore one is added to them — so that we have three. From here they ruled: Monetary litigations are (judged) by three.
