Isaiah 28:9-12 To whom will he teach knowledge, and to whom will he explain the message? Those who are weaned from milk, those taken from the breast?

LEB⁽ⁱ⁾ ⁹ To whom will he teach knowledge, and to whom will he explain the message? Those who are weaned from milk, those taken from the breast? ¹⁰ For it is blah-blah upon blah-blah, blah-blah upon blah-blah, gah-gah upon gah-gah, gah-gah upon gah-gah,* a little here, a little there. ¹¹ For he will speak with _⌊stammering_⌋* and another tongue to this people, ¹² to whom he has said,
"This is rest; give rest to the weary; and this is repose"; yet* they were not willing to hear.
