Charles Ellicott Commentary 1 Kings 2:10

"And David slept with his fathers, and was buried in the city of David." — 1 Kings 2:10 (ASV)

Buried in the city of David —that is, evidently in Mount Zion. In Nehemiah 3:16 the “sepulchres of David” are mentioned, and they are plainly alluded to in Ezekiel 43:7; Ezekiel 43:9. They became the regular tombs of the kings, with some exceptions particularly noticed. It was as a sign of special honour that the high priest Jehoiada, the preserver of the royal dynasty, was buried there (See 2 Chronicles 24:16).
