For His anger is fleeting, but His favor lasts a lifetime. Weeping may stay the night, but joy comes in the morning.
David had flatted himself too confidently in his prosperity, and security bred carelessness that God rightly chastised. When Absalom's rebellion was crushed and David returned to his throne, he dedicated his house with thanksgiving, confessing both his former false confidence and God's faithful discipline toward him.

Commenting on Psalm 30:1-12
For his anger endureth but a moment. David here alludes to those dispensations of God's providence which are the chastisement ordered in his paternal government towards his erring children, such as the plague which fell upon Jerusalem for David's sins; these are but short judgments, and they are removed as soon as real penitence sues for pardon and presents the great and acceptable sacrifice.
It was the laudable practice of the pious Jews, and, though not expressly appointed, yet allowed and accepted, when they had built a new house, to dedicate it to God, Deu 20:5. David did so when his house was built, and he took possession of it (Sa2 5:11); for royal palaces do as much need God's protection, and are as much bound to be at his service, as ordinary houses.
