+Psalm 48Zion Exalted
+
+1. The Lord is great and highly praised
+in the city of our God.
+His holy mountain,
+2. rising splendidly,
+is the joy of the whole earth.
+Mount Zion--the summit of Zaphon--
+is the city of the great King.
+
+3. God is known as a stronghold
+in its citadels.
+
+4. Look! The kings assembled;
+they advanced together.
+
+5. They looked and froze with fear;
+they fled in terror.
+
+6. Trembling seized them there,
+agony like that of a woman in labor,
+
+7. as you wrecked the ships of Tarshish
+with the east wind.
+
+8. Just as we heard, so we have seen
+in 
+the city of the Lord of Armies,
+in the city of our God;
+God will establish it forever.Selah
+
+9. God, within your temple,
+we contemplate your faithful love.
+
+10. Like your name, God, so your praise
+reaches to the ends of the earth;
+your right hand is filled with justice.
+
+11. Mount Zion is glad.
+Judah's villages rejoice
+because of your judgments.
+
+12. Go around Zion, encircle it;
+count its towers,
+
+13. note its ramparts; tour its citadels
+so that you can tell a future generation:
+
+14. "This God, our God forever and ever--
+he will always lead us."
