Tremble, O Earth

PSALM OF THE DAY 1255.5.1.12
When Israel went out from Egypt, the house of Jacob from a people of strange language, Judah became God’s sanctuary, Israel his dominion. The sea looked and fled; Jordan turned back. The mountains skipped like rams, the hills like lambs. Why is it, O sea, that you flee? O Jordan, that you turn back? O mountains, that you skip like rams? O hills, like lambs? Tremble, O earth, at the presence of the Lord, at the presence of the God of Jacob, who turns the rock into a pool of water, the flint into a spring of water. 
—Psalm 114
