Psalms 51:18

Do good in thy good pleasure unto Zion,.... This verse, and Ps 51:19, are thought, by a Spanish Rabbi mentioned by Aben Ezra, to have been added by one of the holy men that lived in the time of the Babylonish captivity; though rather it is thought, by the latter, to be written by David, under a spirit of prophecy, concerning, times to come; and so Kimchi thinks they are prophetic of future things; of the destruction of the first and second temple, and of the acceptableness of sacrifices in the times of the Messiah: and by Zion is meant the church, under the Gospel dispensation, Heb 12:22; and the "good" prayed for includes all the good and glorious things spoken of the church of Christ in the latter day; such as an increase of its numbers, the bringing in the fulness of the Gentiles, the conversion of the Jews, and the kingdoms of this world becoming the kingdoms of our Lord and of his Christ; the spread of the Gospel all over the world, the purity of Gospel doctrine, worship, and ordinances, the spirituality of religion, the power of godliness, and an abounding of brotherly love, and the like.
