Numbers 20:23

He said, “You shall not pass through.” Edom came out against him with many people, and with a strong hand.

Thus Edom refused to give Israel passage through his border, so Israel turned away from him.

They traveled from Kadesh, and the children of Israel, even the whole congregation, came to Mount Hor.

“Aaron shall be gathered to his people; for he shall not enter into the land which I have given to the children of Israel, because you rebelled against my word at the waters of Meribah.

Take Aaron and Eleazar his son, and bring them up to Mount Hor;

and strip Aaron of his garments, and put them on Eleazar his son. Aaron shall be gathered, and shall die there.”
