The LORD is gracious, and full of compassion; slow to anger, and of great mercy. The Lord is gracious - His holy nature is ever disposed to show favor.
Full of compassion - Wherever he sees misery, his eye affects his heart.
Slow to anger - When there is even the greatest provocation.
Of great mercy - Great in his abundant mercy. These four things give us a wonderful display of the goodness of the Divine nature.
