“To whom will he teach knowledge?

To whom will he explain the message?

Will he explain it

To those who are weaned from milk?

Will he explain it

To those taken from the breast?

It is precept upon precept,

Precept upon precept.

It is line upon line,

Line upon line.

It is here a little,

There a little.”

Isaiah speaks about teaching little children. To whom should he explain his message? They have to be at least weaned from breast feeding milk, which would make them very young. The teaching itself is an onomatopoeia, like the sounds of baby children learning how to speak.  This is almost like a nursery rhyme. Thus we have the repetition of phrases such as precept on precept, line on line, and a little here and a little there. Basically, it might refer to the unintelligible words of prophets and charismatics that sound strange.
