Psalms 30:4-6

Verse 4

Sing unto the Lord, O ye saints of his - Ye priests, who wait upon him in his sanctuary, and whose business it is to offer prayers and sacrifices for the people, magnify him for the mercy he has now showed in staying this most destructive plague.

Give thanks at the remembrance of his holiness - "Be ye holy," saith the Lord, "for I am holy." He who can give thanks at the remembrance of his holiness, is one who loves holiness; who hates sin; who longs to be saved from it; and takes encouragement at the recollection of God's holiness, as he sees in this the holy nature which he is to share, and the perfection which he is here to attain. But most who call themselves Christians hate the doctrine of holiness; never hear it inculcated without pain; and the principal part of their studies, and those of their pastors, is to find out with how little holiness they can rationally expect to enter into the kingdom of God. O fatal and soul-destroying delusion! How long will a holy God suffer such abominable doctrines to pollute his Church, and destroy the souls of men?
Verse 5

For his anger endureth but a moment - There is an elegant abruptness in these words in the Hebrew text. This is the literal translation: "For a moment in his anger. Lives in his favor. In the evening weeping may lodge: but in the morning exultation." So good is God, that he cannot delight in either the depression or ruin of his creatures. When he afflicts, it is for our advantage, that we may be partakers of his holiness, and be not condemned with the world. If he be angry with us, it is but for a moment; but when we have recourse to him, and seek his face, his favor is soon obtained, and there are lives in that favor - the life that now is, and the life that is to come. When weeping comes, it is only to lodge for the evening; but singing will surely come in the morning. This description of God's slowness to anger, and readiness to save, is given by a man long and deeply acquainted with God as his Judge and as his Father.
Verse 6

In my prosperity I said, I shall never be moved - Peace and prosperity had seduced the heart of David, and led him to suppose that his mountain - his dominion, stood so strong, that adversity could never affect him. He wished to know the physical and political strength of his kingdom; and, forgetting to depend upon God, he desired Joab to make a census of the people; which God punished in the manner related in 2 Samuel 24, and which he in this place appears to acknowledge.
