And when they lifted up their eyes afar off - "When they saw him at the distance at which they could formerly recognize him without difficulty, disease had so altered his appearance that at first sight they knew him not" - Noyes.

They lifted up their voice - This is a common expression in the Scriptures, to denote grief; Genesis 27:38; Genesis 29:11; Judges 2:4; Ruth 1:9; 1 Samuel 24:16, "et soepe al." We learn to suppress the expressions of grief. The ancients gave vent to their sorrows aloud. - They even hired persons to aid them in their lamentations; and it became a professional business of women to devote themselves to the office of making an outcry on occasions of mourning. The same thing prevails in the East at present. Friends sit around the grave of the dead, or go there at different times, and give a long and doleful shriek or howl, as expressive of their grief.

And they rent every one his mantle - See the notes at Job 1:20.

And sprinkled dust upon their heads toward heaven - Another expression of sorrow; compare Lamentations 2:10; Nehemiah 9:1; 1 Samuel 4:12; Joshua 7:6; Ezekiel 27:30. Thc indications of grief here referred to, were such as were common in ancient times. They resemble, in a remarkable manner, the mode in which Achilles gave utterance to his sorrow, when informed of the death of Patroclus. Iliad xviii. 21-27.

A sudden horror shot through all the chief,

And wrapp'd his senses in the cloud of grief;

Cast on the ground, with furious hands he spread

The scorching ashes o'er his graceful head,

His purple garments, and his golden hairs,

Those he deforms with dust, and these he tears:

On the hard soil his groaning breast he threw,

And roll'd and grovell'd as to earth he grew.

Pope

Thus far the feelings of the three friends were entirely kind, and all that they did was expressive of sympathy for the sufferer.

They rent every one his mantle - I have already had frequent occasions to point out and illustrate, by quotations from the ancients, the actions that were used in order to express profound grief; such as wrapping themselves in sackcloth, covering the face, strewing dust or ashes upon the head, sitting upon the bare ground, etc., etc.; significant actions which were in use among all nations.

And when they lifted up their eyes afar off,.... Either when at some distance from Job's house, and he being without in the open air, as some think; or as they entered his house, he being at the further part of the room, or in another further on, which they could see into:

and knew him not; at first sight; until they came nearer to him, his garments being rent, and his head shaved, and his body covered all over with boils; so that he was so deformed and disfigured that they could not know him at first, and could scarcely believe him to be the same person:

they lifted up their voice and wept: they wept and cried aloud, being greatly affected with the sight of him, and their hearts sympathizing with him under his afflictions, being his cordial friends, and of that disposition, to weep with those that weep:

and they rent everyone his mantle, or "cloak"; in token of mourning, as Job had done before; see Gill on Job 1:20,

and sprinkled dust upon their heads towards heaven; that is, they took up handfuls of dust from off the ground, and threw it up in the air over their heads, which fell upon them and covered them; which was another rite or ceremony used by mourners, as Jarchi observes, and showed the vehemence of their affections and passions, and the confusion they were in at seeing their friend in such a miserable condition; see Joshua 7:6.

Their Arrival:

12 And when they lifted up their eyes afar off, and knew him not, they lifted up their voice, and wept; and they rent every one his mantle, and threw dust upon their heads toward heaven.

They saw a form which seemed to be Job, but in which they were not able to recognise him. Then they weep and rend their outer garments, and catch up dust to throw up towards heaven (1 Samuel 4:12), that it may fall again upon their heads. The casting up of dust on high is the outwards sign of intense suffering, and, as von Gerlach rightly remarks, of that which causes him to cry to heaven.

And when they lifted up their eyes afar off, and knew him not, they lifted up their voice, and wept; and they rent every one his mantle, and sprinkled {q} dust upon their heads toward heaven.

(q) This was also a ceremony which they used in those countries as the renting of their clothes in sign of sorrow etc.

12. toward heaven-They threw ashes violently upwards, that they might fall on their heads and cover them-the deepest mourning (Jos 7:6; Ac 22:23).

2:11-13 The friends of Job seem noted for their rank, as well as for wisdom and piety. Much of the comfort of this life lies in friendship with the prudent and virtuous. Coming to mourn with him, they vented grief which they really felt. Coming to comfort him, they sat down with him. It would appear that they suspected his unexampled troubles were judgments for some crimes, which he had vailed under his professions of godliness. Many look upon it only as a compliment to visit their friends in sorrow; we must look life. And if the example of Job's friends is not enough to lead us to pity the afflicted, let us seek the mind that was in Christ.
