"I also have given you cleanness of teeth in all your cities, And lack of bread in every town; Yet you haven't returned to me," says Yahweh.
"Yet have ye not returned unto me ..."

God's purpose had been that difficulties would turn the hearts of his people toward himself; but, in the case of Israel nothing like that had occurred.
