 In the Liturgy of the Word, the first reading is the Creation story of the Book of Genesis, and Psalm 104, which deals with the same material, is the responsorial psalm.It is used again during Pentecost, at the end of the Easter season, as the responsorial psalm for the Vigil and the Sunday Mass.German philosopher Johann Gottfried Herder remarked, "It is worth studying the Hebrew language for ten years in order to read Psalm 104 in the original".
