Isaiah 28:9-11King James Version (KJV)
9 Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and drawn from the breasts.
10 For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little:
11 For with stammering lips and another tongue will he speak to this people.
