1 To the end, a Psalm of the joy of the Resurrection, and the change, the renewing of the body to an immortal state, and not only of the Lord, but also of the whole Church. For in the former Psalm the tabernacle was finished, wherein we dwell in the time of war: but now the house is dedicated, which will abide in peace everlasting.
