After the Sea of Reeds, Moses led Israel into the wilderness of Shur. For three days they found no water. At Marah the water was bitter, and the people asked what they could drink. Moses cried to God, and God showed him a piece of wood. When Moses threw it into the water, it became sweet.
They camped at Elim, where there were twelve springs and seventy palm trees. Later, in the wilderness of Sin, the people worried about food. God promised bread from the sky: each day they gathered only what they needed. In the evening quail covered the camp, and in the morning a fine, flaky food lay on the ground. They asked, “What is it?” and Moses said it was the bread God gave them. On the sixth day they gathered double, and on the seventh day they rested.
At Rephidim there was no water again. God told Moses to strike the rock at Horeb, and water flowed. Then Amalek attacked. Joshua led the fighters while Moses stood on a hill with the rod of God. When Moses’ hands grew heavy, Aaron and Hur held them up until sunset, and Israel prevailed. Moses built an altar and named it Adonai-nissi, a Hebrew name meaning “The Lord is my banner.”
