Charles H. Spurgeon on Psalms 38:13

But I, as a deaf man, heard not. The inspired writer here compares himself to a dumb and deaf man for two reasons. In the first place, he intimates that he was so overwhelmed with the false and wicked judgments of his enemies, that he was not even permitted to open his mouth in his own defence. In the second place, he alleges before God his own patience, as a plea to induce God the more readily to have pity upon him; for such meekness and gentleness, not only with good reason, secures favour to the afflicted and the innocent, but it is also a sign of true piety. John Calvin.
