Matthew Poole and continuators on John 13:22

22 Then the disciples looked one on another, doubting of whom he spake .

It seemeth they had no suspicion of Iudas, but our Saviour telling them that it was one of them, they begin to look about one upon another, rather suspecting themselves than Iudas. There may be a great deal of villany, and the greatest villany in the hearts of Professors, in whose conversation appeareth nothing that may give a just suspition to others, and the true Disciples of Christ will have so much candor and brotherly love, that they will not rashly judge and censure their brethren.
