Charles H. Spurgeon on Psalms 38:13

But I, as a deaf man, heard not. Well and bravely was this done. A sacred indifference to the slanders of malevolence is true courage and wise policy. It is well to be as if we could not hear or see. Perhaps the psalmist means that this deafness on his part was unavoidable because he had no power to answer the taunts of the cruel, but felt much of the truth of their ungenerous accusations. And I was as a dumb man that openeth not his mouth. David was bravely silent, and herein was eminently typical of our Lord Jesus, whose marvellous silence before Pilate was far more eloquent than words. To abstain from self defence is often most difficult, and frequently most wise.
