Isaiah 28:9-11. “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. For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little; For with stammering lips and another tongue will he speak to this people.”
Those whom Isaiah rebuked responded to him in a mocking, sarcastic manner. Put in our own terms, they could have been saying, “Who does he think he is to rebuke us? WE are the priests and prophets; WE are the leaders! He speaks to us as if we were nothing but children, who need to be taught a little at a time!”
Children do need to be taught as their understanding develops. At first, a firm “No!” and removing the child from danger will suffice. Later, they need to be taught to avoid danger themselves, to learn to know what is off limits. This is done by repetition, the same lesson being taught over and over until the child understands. Then, when he chooses to disobey anyway, discipline must follow.
Verse 11 is a foreshadowing of what was to come when the Assyrians took over the task of commanding the people of Judah. Their language was not Hebrew, and there would be trouble with communication–to Judah’s dismay. Because they had chosen to disobey God, discipline would follow.
