Isaiah 50:3-5

Revised Standard Version Catholic Edition

³ I clothe the heavens with blackness,
    and make sackcloth their covering.”

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 that is weary.
Morning by morning he wakens,
    he wakens 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.
