Then God said, "That's enough. Do not speak to me anymore about this matter."
I found this a profound, fascinating story about Moses pleading with God to allow him to cross over and see "the good land beyond the Jordan [River]–that fine hill country and Lebanon." This is from NIV (3:21-29):
At that time I pleaded with the Lord: “Sovereign Lord, you have begun to show to your servant your greatness and your strong hand. For what god is there in heaven or on earth who can do the deeds and mighty works you do? Let me go over and see the good land beyond the Jordan—that fine hill country and Lebanon.”
But because of you the Lord was angry with me and would not listen to me. “That is enough,” the Lord said. “Do not speak to me anymore about this matter. Go up to the top of Pisgah and look west and north and south and east. Look at the land with your own eyes, since you are not going to cross this Jordan. But commission Joshua, and encourage and strengthen him, for he will lead this people across and will cause them to inherit the land that you will see.” So we stayed in the valley near Beth Peor."
What a moment it is when God says, "That is enough. Do not speak to me anymore about this matter." God relented to let Moses see what he would be missing, but He did not change His mind over this particular matter with Moses.
