Verse 13. Upon the ground - In the posture of mourners condoling with him. Seven days - Which was the usual time of mourning for the dead, and therefore proper both for Job's children, and for Job himself, who was in a manner dead, while he lived: not that they continued in this posture so long together, which the necessities of nature could not bear; but they spent the greatest part of that time in sitting with him, and silent mourning over him. None spake - About his afflictions and the causes of them. The reason of this silence was the greatness of their grief for him, and their surprize and astonishment at his condition; because they thought it convenient to give him time to vent his own sorrows, and because as yet they knew not what to say to him: for though they had ever esteemed him to be a truly good man, and came with full purpose to comfort him, yet the prodigious greatness of his miseries, and that hand of God which they perceived in them, made them now question his sincerity, so that they could not comfort him as they had intended, and yet were loth to grieve him with reproofs.
