Jerusalem Mountain HighBy Rabbi Jack Abramowitz
David says that people who trust in G-d are like Mount Zion in that they cannot be moved. Just as the mountain stands firm, so too are those who put their trust in G-d.
Just as Jerusalem is surrounded by mountains, G-d always surrounds His people. The righteous will not fall prey to evil rulers, so that they should not learn from the deeds of the wicked.
David prays that G-d will do good things for the upright of His people, but lead the crooked ones away. When this happens, there will be peace on Israel.
