Charles H. Spurgeon on Psalms 38:20

They also that render evil for good are mine adversaries. Such would a wise man wish his enemies to be. Why should we seek to be beloved of such graceless souls? It is a fine plea against our enemies when we can without injustice declare them to be like the devil, whose nature it is to render evil for good. Because I follow the thing that good is. If men hate us for this reason we may rejoice to bear it: their wrath is the unconscious homage which vice renders to virtue. This verse is not inconsistent with the writer's previous confession; we may feel equally guilty before God, and yet be entirely innocent of any wrong to our fellow men. It is one sin to acknowledge the truth, quite another thing to submit to be belied. The Lord may smite me justly, and yet I may be able to say to my fellow man, "Why smitest thou me?"
