52. πρὸς ἀλλήλους. One with another (Joh 4:33, Joh 16:17): their excitement increases; they have got beyond murmuring about Him (Joh 5:4), but they are not all equally hostile (Joh 7:12; Joh 7:43; Joh 10:19). “They strove, and that with one another, for they understood not, neither wished to take the Bread of concord” (S. Augustine).
Πῶς. This is the old vain question (Joh 3:4; Joh 3:9) which continues to distract the Church and the world. All that men need know is the fact; but they insist in asking as to the manner. ‘Cur’ et ‘Quomodo’ exitiales voculae—‘Why’ and ‘How’ are deadly little words (Luther). Οὗτος is contemptuous (Joh 6:42): φαγεῖν is their own addition; they wish to bring out in full the strangeness of His declaration.
