Job 6:16

“Which are blackish by reason of the ice, etc.] When frozen over, they look of a blackish colour, and is what is called a black frost; and these either describe Job and his domestics, as some f269 think whom Eliphaz and his two friends compared to the above streams water passed away from, or passed by and neglected, and showed no friendship to; who were in black, mournful and rueful circumstances, through the severe hand of God upon them. The word is rendered, “those which mourn”, (<180511>Job 5:11); or rather the friends of Job compared to foul and troubled waters frozen over which cannot be so well discerned, or which were black through being frozen, and which describes the inward frame of…”

“blackish--literally, "Go as a mourner in black clothing" (Psa 34:14).

Jerome renders it, Qui timent pruinam - “which fear the frost, when the snow comes upon them.” The Septuagint renders it, “they who had venerated me now rushed upon me like snow or hoar frost, which melting at the approach of heat, it was not known whence it was.” The expression in the Hebrew means that they were rendered dark and turbid by the accumulated torrents caused by the…”

“Which - Which in winter when the traveller neither needs nor desires it, are full of water congealed by the frost. Snow - Under which the water from snow, which formerly fell, and afterward was dissolved, lies hid. So he speaks not of those brooks which are fed by a constant spring, but of them which are filled by accidental falls of water or snow. Job 6:17”
