Verse 17. - What time they wax warm, they vanish: when it is hot, they are consumed out of their place (see the passage quoted from Dr. Geikie in the comment on ver. 15).

6:14-30 In his prosperity Job formed great expectations from his friends, but now was disappointed. This he compares to the failing of brooks in summer. Those who rest their expectations on the creature, will find it fail when it should help them; whereas those who make God their confidence, have help in the time of need, Heb 4:16. Those who make gold their hope, sooner or later will be ashamed of it, and of their confidence in it. It is our wisdom to cease from man. Let us put all our confidence in the Rock of ages, not in broken reeds; in the Fountain of life, not in broken cisterns. The application is very close; for now ye are nothing. It were well for us, if we had always such convictions of the vanity of the creature, as we have had, or shall have, on a sick-bed, a death-bed, or in trouble of conscience. Job upbraids his friends with their hard usage. Though in want, he desired no more from them than a good look and a good word. It often happens that, even when we expect little from man, we have less; but from God, even when we expect much, we have more. Though Job differed from them, yet he was ready to yield as soon as it was made to appear that he was in error. Though Job had been in fault, yet they ought not to have given him such hard usage. His righteousness he holds fast, and will not let it go. He felt that there had not been such iniquity in him as they supposed. But it is best to commit our characters to Him who keeps our souls; in the great day every upright believer shall have praise of God.What time they wax warm they vanish,.... The ice and the snow, which, when the weather becomes warm, they melt away and disappear; and in like manner, he suggests his friends ceased to be friends to him in a time of adversity; the sun of affliction having looked upon him, they deserted him, at least did not administer comfort to him:

when it is hot they are consumed out of their place; when it is hot weather, and the sun has great strength then the waters, which swelled through the floods and fall of rain and snow, and which when frozen, looked black and big as if they had great depth in them, were quickly dried up, and no more to be seen in the place where they were; which still expresses the short duration of friendship among men, which Job had a sorrowful experience of.
