Moses and Aaron Denied Passage

Numbers 20:1-13 - In the first month the whole Israelite community arrived at the Desert of Zin, and they stayed at Kadesh. There Miriam died and was buried.

Now there was no water for the community, and the people gathered in opposition to Moses and Aaron. They quarreled with Moses and said, "If only we had died when our brothers fell dead before the LORD! Why did you bring the LORD's community into this desert, that we and our livestock should die here? Why did you bring us up out of Egypt to this terrible place? It has no grain or figs, grapevines or pomegranates. And there is no water to drink!"

Moses and Aaron went from the assembly to the entrance to the Tent of Meeting and fell facedown, and the glory of the LORD appeared to them. The LORD said to Moses, "Take the staff, and you and your brother Aaron gather the assembly together. Speak to that rock before their eyes and it will pour out its water. You will bring water out of the rock for the community so they and their livestock can drink."

So Moses took the staff from the LORD's presence, just as he commanded him. He and Aaron gathered the assembly together in front of the rock and Moses said to them, "Listen, you rebels, must we bring you water out of this rock?" Then Moses raised his arm and struck the rock twice with his staff. Water gushed out, and the community and their livestock drank.

But the LORD said to Moses and Aaron, "Because you did not trust in me enough to honor me as holy in the sight of the Israelites, you will not bring this community into the land I give them."

These were the waters of Meribah, where the Israelites quarreled with the LORD and where he showed himself holy among them.

I wonder if Moses and Aaron had assumed, before this time, that they would enter Canaan with the rest of the Israelites. Earlier God had said that those 20 years old or more who had grumbled against him would not enter the land. Moses and Aaron surely wouldn't have fit into that category. (What about Miriam?) But only Joshua and Caleb were specifically mentioned as being exempt. I wonder if that made Moses and Aaron (and Miriam?) nervous.

I'm curious. Could you please tell me what brought you to this page by mentioning it in a comment? I won't publish the comment, if you ask me not to.
