Psalm 50, a Psalm of Asaph, is the 50th psalm from the Book of Psalms in the Bible, beginning in English in the King James Version: "The mighty God, even the LORD, hath spoken, and called the earth from the rising of the sun unto the going down thereof." In the slightly different numbering system used in the Greek Septuagint and Latin Vulgate translations of the Bible, this psalm is Psalm 49. The opening words in Latin are Deus deorum, Dominus, locutus est / et vocavit terram a solis ortu usque ad occasum. The psalm is a prophetic imagining of God's judgment on the Israelites.
The psalm forms a regular part of Jewish, Catholic, Lutheran, Anglican and other Protestant liturgies. It has been set to music completely and in single verses. The phrase A solis ortu usque ad occasum, taken from verse 1, or Psalm 113:3 is part of a Spanish coat of arms.
