Ecclesiastes 7:21 - Matthew Poole's English Annotations on the Holy Bible

Take no heed; do not severely observe nor strictly search into them, nor listen to hear them, as many persons out of curiosity use to do. Unto all words that are spoken, to wit, concerning thee, or against thee. Under this one kind of offences of the tongue, which are most frequent, he seems to understand all injuries which we suffer from others, and adviseth us that we do not too rigidly examine them, nor too deeply resent them, but rather neglect and forget them. Lest thou hear thy servant curse thee; which will vex and grieve thee, and may provoke thee to vengeance and cruelty against him.
