Commenting on Psalm 30:1-12
O Lord, thou hast brought up my soul from the grave. Mark, it is not "I hope so; "but it is, "Thou hast; thou hast; thou hast" —three times over. David is quite sure, beyond a doubt, that God has done great things for him, whereof he is exceeding glad.
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.
