The title of Psalm 75 says it is a Psalm by Asaph, a song, set to the tune Do Not Destroy. It is a dialogue. The community begins with thanks because God's Name is near, meaning his presence and reputation are close at hand. Then God speaks in the first person: When I choose the appointed time, I will judge blamelessly. The earth and all its inhabitants quake. I firmly hold its pillars.
God's words are a warning to pride. Don't boast; don't lift up the horn. In the Bible, a horn often stands for power and status, like the horns of a strong animal. The psalm insists that exaltation does not come from the east, west or south. Power is not gained by geography, wealth or alliances. God is the judge. He puts down one, and lifts up another.
The poem uses the image of a cup of foaming wine in Yahweh's hand, which the wicked of the earth must drink to its dregs. It is a picture of judgment that cannot be avoided. The psalm closes with the singer's promise to declare and sing praises to the God of Jacob, and with God's word that the horns of the wicked will be cut off while the horns of the righteous are lifted up.
