Commentary for Psalms 30:1

A song of dedication of the House which the Levites will say at the dedication of the House in the days of Solomon.

When he told him that Shlomo his son would build the house he was clothed with joy in place of his mourning because his son was like him, and his enemies could not disparage him. And he said that suffering of the soul is similar to physical suffering, and even worse in the sense that “A man's spirit will sustain his illness…” (Proverbs 18:14)
