Charles H. Spurgeon on Psalms 69:11

I made sackcloth also my garment. This David did literally, but we have no reason to believe that Jesus did. In a spiritual sense he, as one filled with grief, was always a sackcloth wearer. And I became a proverb to them. He was ridiculed as "the man of sorrows, "quoted as "the acquaintance of grief." He might have said, "here I and sorrow sit." This which should have won him pity only earned him new and more general scorn. To interweave one's name into a mocking proverb is the highest stretch of malice, and to insult one's acts of devotion is to add profanity to cruelty.
