From this passage we learn that Jesus will judge with His disciples; whence He says in another place to the Jews, “Therefore shall they be your judges.” [Matt 12:27] And whereas He says they shall sit upon twelve thrones, we need not think that twelve persons only shall judge with Him. For by the number twelve is signified the whole number of those that shall judge; and that because the number seven which generally represents completeness contains the two numbers four and three, which multiplied together make twelve. For if it were not so, as Matthias was elected into the place of the traitor Judas, the Apostle Paul who laboured more than they all should not have place to sit to judge; but he shews that he with the rest of the saints pertains to the number of judges, when he says, “Know ye not that we shall judge Angels?” [1 Cor 6:3]
