My son, do not reject or take lightly the discipline of the Lord [learn from your mistakes and the testing that comes from His correction through discipline];
Nor despise His rebuke,

He who says to the wicked, “You are righteous,”
Peoples will curse him, nations will denounce him;

Like a [common] clay vessel covered with the silver dross [making it appear silver when it has no real value]
Are burning lips [murmuring manipulative words] and a wicked heart.
