Job 6:16 in the King James Version
Which are blackish by reason of the ice, and wherein the snow is hid:
Context
15 My brothers have dealt deceitfully as a brook, as the channel of brooks that pass away;
16 which are black by reason of the ice, in which the snow hides itself.
17 In the dry season, they vanish. When it is hot, they are consumed out of their place.
