The psalm begins with a strange observation: transgression speaks to the wicked deep in his heart, and there is no fear of God before his eyes. He flatters himself and does not discover his guilt or hate it. His words are mischief and deceit, he has ceased to act wisely and do good, and even in bed he plots evil; he sets himself on a way that is not good and does not reject evil.
Suddenly the tone changes. The Lord's steadfast love reaches to the heavens and his faithfulness to the clouds; his righteousness is like the mountains of God and his judgments like the great deep. The Lord saves humans and animals. How precious is his steadfast love: the children of mankind take refuge in the shadow of his wings, feast on the abundance of his house and drink from the river of his delights. For with him is the fountain of life, and in his light we see light.
The psalm ends with a prayer: that the Lord continue his steadfast love to those who know him and his righteousness to the upright in heart, that the foot of arrogance not come upon David nor the hand of the wicked drive him away. There the evildoers lie fallen; they are thrown down and cannot rise.
