Charles Ellicott Commentary 2 Chronicles 26:23

"So Uzziah slept with his fathers; and they buried him with his fathers in the field of burial which belonged to the kings; for they said, He is a leper: and Jotham his son reigned in his stead." — 2 Chronicles 26:23 (ASV)

So Uzziah slept. — 2 Kings 15:7.

In the field of the burial. — In the burial field or graveyard belonging to the kings, and near their tombs; but not in the royal tombs themselves, because a leper would have polluted them.

Kings simply says, as usual, in the city of David.
