David
Psalm 53:1ESV·traditional attribution

The fool says in his heart, “There is no God.” They are corrupt, doing abominable iniquity; there is none who does good.

John Calvin Reformed @genevareformer

PSALM 53 This psalm being almost identical with the fourteenth, it has not been considered necessary to subjoin any distinct commentary. Some slight differences will be found, on comparison, between this and the 14th psalm; the chief of which is in the 5th verse. For Calvin’s explanation of this verse, see volume 1, p. 199.

C.H. Spurgeon Reformed Baptist @princeofpreachers

The fool hath said in his heart, There is no God. And this he does because he is a fool. Being a fool he speaks according to his nature; being a great fool he meddles with a great subject, and comes to a wild conclusion.

Matthew Henry Presbyterian @wholebiblehenry

This psalm was opened before, and therefore we shall here only observe, in short, some things concerning sin, in order to the increasing of our sorrow for it and hatred of it. 1. The fact of sin. Is that proved? Can the charge be made out?
