Isaiah 48:10-12

New Catholic Bible

¹⁰ See, I have tested you,
    but not in the manner that silver is tested;
    I have tested you in the furnace of affliction.
¹¹ For my sake, for my own sake, I do this,
    for why should my name be profaned?
    I will not yield my glory to another.
¹² Listen to me, O Jacob,
    and Israel, whom I have called.
I am he; I am the first
    and I am the last.
