For he shall be like the heath in the desert, and shall not see when good cometh; but shall inhabit the parched places in the wilderness, in a salt land and not inhabited. Be shall be like the heath in the desert - כערער kearar; or, like a blasted tree, without moisture, parched and withered.
Shall not see when good cometh - Shall not be sensible of it: the previous drought having rendered it incapable of absorbing any more vegetable juices.
A salt land - Barren; and therefore unfit to be inhabited.
