Isaiah 28:9-12

9Whom shall he teach knowledge? and whom shall he make to understand the report? Them that are weaned from the milk, withdrawn from the breasts?

10For [it is] precept upon precept, precept upon precept; line upon line, line upon line; here a little, there a little. ...

11For with stammering lips and a strange tongue will he speak to this people;

12to whom he said, This is the rest: cause the weary to rest; and this is the refreshing. But they would not hear.
