Job 6:16 in the World English Bible
which are black by reason of the ice, in which the snow hides itself.
Context
15 My brethren have dealt deceitfully as a brook, and as the stream of brooks they pass away;
16 Which are blackish by reason of the ice, and wherein the snow is hid:
17 What time they wax warm, they vanish: when it is hot, they are consumed out of their place.
