+Psalm 125Israel's Stability
+
+1. Those who trust in 
+the Lord are like Mount Zion.
+It cannot be shaken; it remains forever.
+
+2. The mountains surround Jerusalem
+and 
+the Lord surrounds his people,
+both now and forever.
+
+3. The scepter of the wicked will not remain
+over the land allotted to the righteous,
+so that the righteous will not apply their hands to injustice.
+
+4. Do what is good, Lord, to the good,
+to those whose hearts are upright.
+
+5. But as for those who turn aside to crooked ways,
+the Lord will banish them with the evildoers.
+Peace be with Israel.
