Numbers 20:24

20:24 “Aaron will be gathered to his ancestors, for he will not enter into the land I have given to the Israelites because both of you rebelled against my word at the waters of Meribah.

Numbers 20:28

20:28 And Moses removed Aaron’s garments and put them on his son Eleazar. So Aaron died there on the top of the mountain. And Moses and Eleazar came down from the mountain.

sn This is the standard poetic expression for death. The bones would be buried, often with the bones of relatives in the same tomb, giving rise to the expression.

tn The verb is in the second person plural form, and so it is Moses and Aaron who rebelled, and so now because of that Aaron first and then Moses would die without going into the land.

tn Heb “mouth.”
