Keil & Delitzsch

Their Silence: 13 And they sat with him upon the ground seven days and seven nights; and none spake a word unto him: for they saw that his pain was very great. Ewald erroneously thinks that custom and propriety prescribed this seven days' silence; it was (as Eze 3:15) the force of the impression produced on them, and the fear of annoying the sufferer. But their long silence shows that they had not fully realized the purpose of their visit. Their feeling is overpowered by reflection, their sympathy by dismay. It is a pity that they let Job utter the first word, which they might have prevented by some word of kindly solace; for, becoming first fully conscious of the difference between his present and former position from their conduct, he breaks forth with curses.
