John 13:10 Commentary - Garner-Howes Baptist Commentary
1 ) "Jesus saith to him," (legei auto lesous) "Jesus responded to him," to his earnest outburst for a complete cleansing, when the meaning of our Lord's washing their feet was clear to him.
2) "He that is washed," (ho leloumenos) "The one who is (exists) washed," already, that is already clean, that is bathed all over, redeemed by faith in His blood, Rom 3:25; Tit 3:5.
3) "Needeth not save to wash his feet," (ouk echei chreian ei me tous poclas nipsasthai) "Has not a need (really) to wash his feet," or to object that another wash his feet, without embarrassment. As the priest was physically clean before, and while making the sacrifice, yet before he entered the tabernacle, from the brazen altar of sacrifice, he washed his hands and feet at the laver, indicating that those redeemed need cleansing from daily defilement, and is a symbol of it.
4) "But is clean every whit:" (all' estin katharos holos) "But he exists as wholly cleansed," Eph 5:20, already clean, 1Co 1:30; 1Co 6:11; 1Jn 3:9; Yet they needed daily cleansing, as a traveler needed to wash his feet upon entrance to a home, because of dust on his feet from the sandals he wore, 2Co 7:1; Jas 1:21; Act 15:8-9.
5) "And ye are clean," (kai humeis katharoi este) "And you all are clean," you disciples, as a whole, as a church fellowship. Yet they needed humility, and daily confession, and cleansing from defilements, contracted or motivated from the world, Mat 6:11-12; Jas 5:16-17; 1Jn 1:9.
6) "But not all." (all' ouch pantes) "But not all," are really cleansed, Joh 6:64. Not all of the disciples, especially that one who was also an apostle, Judas Iscariot, who was then plotting to betray and sell Him, like a man would sell a dog, Joh 12:4; Mar 14:10-11.
