“Which are blackish by reason of the ice, and wherein the snow is hid:”
King James Version (KJV)
6:16 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.
