| Barnes' Notes on the Bible The princes refrained talking - As a mark of respect, or in awe of his presence. And laid their hand on their mouth - To lay the finger or the hand on the mouth is every where an action expressive of silence or respect; Notes, Job 21:5. "In one of the subterranean vaults of Egypt, where the mummies lie buried, they found in the coffin an embalmed body of a woman, before which was placed a figure of wood, representing a youth on his knees, laying a finger on his mouth, and holding in his other hand a sort of chafing dish, which was placed on his head, and in which, without doubt, had been some perfumes." Maillet.

Gill's Exposition of the Entire BibleThe princes refrained talking,.... Who were in court before Job came in, and were either talking with one another about indifferent matters, or were giving their opinion in a case before them; but no sooner did Job make his appearance, but they left off talking, and would not proceed any further; they laid a restraint upon their words, and curbed themselves from speaking any more till they had heard his opinion: and laid their hand on their mouth; as a token of silence, Judges 18:19.

Matthew Henry's Concise Commentary29:7-17 All sorts of people paid respect to Job, not only for the dignity of his rank, but for his personal merit, his prudence, integrity, and good management. Happy the men who are blessed with such gifts as these! They have great opportunities of honouring God and doing good, but have great need to watch against pride. Happy the people who are blessed with such men! it is a token for good to them. Here we see what Job valued himself by, in the day of his prosperity. It was by his usefulness. He valued himself by the check he gave to the violence of proud and evil men. Good magistrates must thus be a restraint to evil-doers, and protect the innocent; in order to this, they should arm themselves with zeal and resolution. Such men are public blessings, and resemble Him who rescues poor sinners from Satan. How many who were ready to perish, now are blessing Him! But who can show forth His praises? May we trust in His mercy, and seek to imitate His truth, justice, and love. |
