Nehemiah 3:16

After him repaired Nehemiah the son of Azbuk, the ruler of the
half part of Bethzur.
] A strong fortified place in the tribe of Judah, ( Joshua 15:58 ) ,

unto the place over against the sepulchres of David;
where he and his family, and the kings of his race, were buried, which remained to this time untouched by the Babylonians, and to many ages after; see ( Acts 2:29 )

and to the pool that was made;
not a natural, but an artificial one, which was made by Hezekiah, ( 2 Kings 20:20 ) ,

and unto the house of the mighty;
where was a garrison of soldiers in former time for defence.
