4   The Lord GOD has given me
    the tongue of those who are taught,
  that I may know how to sustain with a word
    him who is weary.
  Morning by morning he awakens;
    he awakens my ear
    to hear as those who are taught.
5   The Lord GOD has opened my ear,
    and I was not rebellious;
    I turned not backward.

— Isaiah 50:4-5
