Psalms 78:9-16

The warriors of Ephraim, though armed with bows, turned their backs and fled on the day of battle. They did not keep God’s covenant and refused to live by his instructions. They forgot what he had done— the great wonders he had shown them, the miracles he did for their ancestors on the plain of Zoan in the land of Egypt. For he divided the sea and led them through, making the water stand up like walls! In the daytime he led them by a cloud, and all night by a pillar of fire. He split open the rocks in the wilderness to give them water, as from a gushing spring. He made streams pour from the rock, making the waters flow down like a river!
