For with stammering lips and another tongue will he speak to this people. To whom he said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing: yet they would not hear. But the word of the LORD was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little; that they might go, and fall backward, and be broken, and snared, and taken.
God told the people since they did not want to listen to His simple, understandable language, He would send a foreign invader, Assyria, into their midst. Their alien tongue would be a sign of judgment on a people who refused God when He offered rest to them and the ability to administer rest to others. As for the LORD, He would continue to speak in the simplest, clearest words; but that would be in order that all responsibility for their rejection would be on them.
