Drought and heat consume the snow waters; so doth the grave those which have sinned. This rendering is further confirmed by the next verse. Accepting it, we must suppose Job to pass at this point to the consideration of the ultimate end of the wicked, though in verse 21 he returns to the consideration of their ill doings.
