Psalms 51:5

Psalms 51:5. Behold,

David is full of astonishment and amazement; his one great sin has opened his eyes to see the sinfulness of his whole nature.

Psalms 51:5. I was shapen in iniquity; and in sin did my mother conceive me.

"I was ‘shapen in iniquity’ when I was shapen, and ‘conceived in sin’ when I was conceived." He sees that the sin is in himself, and that it does not happen to him as an accident, but flows from him as naturally as foul water runs from a polluted spring.
