Charles H. Spurgeon on Psalms 104:35

This is the first place where HALLELUJAH ("Praise ye the Lord") occurs in the Book of Psalms. It is produced by a retrospect of Creation, and by the contemplation of God's goodness in the preservation of all the creatures of his hand, and also by a prospective view of that future Sabbath, when, by the removal of evil men from communion with the good, God will be enabled to look on his works, as he did on the first Sabbath, before the Tempter had marred them, and see "everything very good." See Ge 1:31 2:2-3 —Christopher Wordsworth.
