Hands at prayerFor since human nature rejects and avoids what is difficult, even if beneficial, and accepts virtually nothing unless it seems to offer pleasure, through David the Lord prepares from men this potion which is sweet by reason of its melody and effective in the cure of disease by reason of its strength.

For a Psalm is sweet to the ear, it penetrates the soul when it gives pleasure, it is easily remembered when sung often, and what the harshness of the Law cannot force from the minds of man it excludes by the suavity of song. For whatever the Law, the Prophets and even the Gospels teach is contained as a remedy in the sweetness of these songs.
