Psalms 78:9-16

Take, for example, the sons of Ephraim. Though they were all equipped warriors, each with weapons, when the battle began they retreated and ran away in fear. They didn’t really believe the promises of God; they refused to trust him and move forward in faith. They forgot his wonderful works and the miracles of the past, even their exodus from Egypt, the epic miracle of his might. They forgot the glories of his power at the place of passing over. God split the sea wide open, and the waters stood at attention on either side as the people passed on through! By day the moving glory-cloud led them forward. And all through the night the fire-cloud stood as a sentry of light. In the days of desert dryness, he split open the mighty rock, and the waters flowed like a river before their very eyes. He gave them all they wanted to drink from his living springs.
