David
Psalm 38:20ESV·traditional attribution

Those who render me evil for good accuse me because I follow after good.

John Calvin Reformed @genevareformer

PSALM 38 David, suffering under some severe and dangerous malady, as may be conjectured, acknowledges that he is chastened by the Lord, and entreats him to turn away his anger from him. In order the more effectually to induce God to have mercy upon him, he bewails before him the severity of his afflictions in a variety of particulars. These we shall consider separately, and in order.

C.H. Spurgeon Reformed Baptist @princeofpreachers

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.

Matthew Henry Presbyterian @wholebiblehenry

In these verses, I. David complains of the power and malice of his enemies, who, it should seem, not only took occasion from the weakness of his body and the trouble of his mind to insult over him, but took advantage thence to do him a mischief.
