Deuteronomy 34:4-6

Then the LORD said to Moses, “This is the land I promised to Abraham, Isaac, and Jacob when I said to them, ‘I will give this land to your descendants.’ I have let you look at it, Moses, but you will not cross over there.” Then Moses, the servant of the LORD, died there in Moab, as the LORD had said. He buried Moses in Moab in the valley opposite Beth Peor, but even today no one knows where his grave is.
