Numbers 20:23-24

²³which is in the ends of the land of Edom (or which is near Edom’s border); where the Lord spake to Moses, and said,

²⁴Aaron (shall) go to his people; for he shall not enter into the land which I gave to the sons of Israel, for he was unbelieveful to my word, at the waters of against-saying. (Aaron shall now go to his people, that is, he shall die; for he shall not enter into the land which I gave to the Israelites, for he did not believe my word at the waters of Meribah.)
