'Consume' in the Bible

and now, let Me alone, and My anger doth burn against them, and I consume them, and I make thee become a great nation.'

why do the Egyptians speak, saying, For evil He brought them out to slay them among mountains, and to consume them from off the face of the ground? turn back from the heat of Thine anger, and repent of the evil against Thy people.

unto a land flowing with milk and honey, for I do not go up in thy midst, for thou art a stiff-necked people -- lest I consume thee in the way.'
