Matthew Poole and continuators on John 13:10

10 Jesus saith to him, He that is washed, needeth not, save to wash his feet , but is clean every whit: and ye are clean, but not all .

Look as it is with persons that have been washing themselves in a Bath, when they are washed, yet walking abroad bare-foot, or with thin Sandals, or coverings for their feet, will be again subject to pollute and dirty their feet; so as they will have frequent need to wash them again; but they need not soon again wash their whole bodies: so it is as to Souls that are washed with my blood, washed, and sanctified, justified in the Name of the Lord Iesus, and by the Spirit of God ▪ (as the Apostle speaketh, 1 Cor. 6.11.) their state is not to be renewed; they need not be justified a second time, but they will have need to have their feet washed in regard of their remainder of sin, and lust that is in them, and will be so while they are in the World, and the temptations which every where lie in the World, as snares for their feet; they will have need of a daily washing by repentance, and fresh applications of their Souls to my blood, by the repeated exercises of faith, according to their renewed and repeated acts of sin.

You, who are my Apostles, are clean, you are washed, you are justified; I have forgiven your sins, accepted your persons, but not all; the most of you are so, but not all.
