What are the form and literary genre of Psalm 67? Is it a song of thanksgiving for the harvest? a plea for rain? A careful analysis of the internal logic of the text leads one to understand «harvest» in a metaphoric sense. Israel prays to God that His light enlighten the nations (2-3), invites the nations all together to praise the one God (4-6), and gives thanks as it sees that in faith its prayer is already heard (7-8). This Psalm is one of the most outstanding universalist texts of the Bible: in it Israel sees itself as the the people by which light is transmitted to the whole world.
