For his anger is but for a moment, and his favor is for a lifetime. Weeping may tarry for the night, but joy comes with the morning.
PSALM 30. David having been delivered from great danger, not only renders thanks to God apart by himself, but at the same time invites and exhorts all the pious to perform the same duty. He then confesses that he had flattered himself too confidently in his prosperity, and that his security had justly been chastised. In the third place, having briefly expressed his sorrow, he returns again to thanksgiving.
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.
