John 13:22 Commentary - Garner-Howes Baptist Commentary

1) "Then the disciples looked one on another," (eblepon eis allelous hoi mathetai) "The disciples looked at one another," with questioning, inquiring glances and penetrating gazes, in bewilderment, not yet suspecting with any certainty that it was Judas.

2) "Doubting of whom he spake.” (aporounenoi peri tinos legei) "Being perplexed, pondering about, or concerning who he was speaking," doubting, uncertain, not knowing of whom He spoke in alluding to the Scripture, Psa 41:9. Judas was at no real loss to know of whom He spoke.
