Water from a Rock

The entire Israelite community entered the Wilderness of Zin in the first month, and they settled in Kadesh. Miriam died and was buried there. There was no water for the community, so they assembled against Moses and Aaron. The people quarreled with Moses and said, “If only we had perished when our brothers perished before the LORD. Why have you brought the LORD’s assembly into this wilderness for us and our livestock to die here? Why have you led us up from Egypt to bring us to this evil place? It’s not a place of grain, figs, vines, and pomegranates, and there is no water to drink!” Then Moses and Aaron went from the presence of the assembly to the doorway of the tent of meeting. They fell facedown, and the glory of the LORD appeared to them. The LORD spoke to Moses, “Take the staff and assemble the community. You and your brother Aaron are to speak to the rock while they watch, and it will yield its water. You will bring out water for them from the rock and provide drink for the community and their livestock.” So Moses took the staff from the LORD’s presence just as he had commanded him. Moses and Aaron summoned the assembly in front of the rock, and Moses said to them, “Listen, you rebels! Must we bring water out of this rock for you?” Then Moses raised his hand and struck the rock twice with his staff, so that abundant water gushed out, and the community and their livestock drank. But the LORD said to Moses and Aaron, “Because you did not trust me to demonstrate my holiness in the sight of the Israelites, you will not bring this assembly into the land I have given them.” These are the Waters of Meribah, where the Israelites quarreled with the LORD, and he demonstrated his holiness to them.
(Numbers 20:1-13)

When Jesus came to the region of Caesarea Philippi, he asked his disciples, “Who do people say that the Son of Man is?” They replied, “Some say John the Baptist; others, Elijah; still others, Jeremiah or one of the prophets.” “But you,” he asked them, “who do you say that I am?” Simon Peter answered, “You are the Messiah, the Son of the living God.” Jesus responded, “Blessed are you, Simon son of Jonah, because flesh and blood did not reveal this to you, but my Father in heaven. And I also say to you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overpower it. I will give you the keys of the kingdom of heaven…”
(Matthew 16:13-19)
