Nehemiah 7:1

7:1 When the wall had been rebuilt and I had positioned the doors, and the gatekeepers, the singers, and the Levites had been appointed,

Nehemiah 12:45

12:45 They performed the service of their God and the service of purification, along with the singers and gatekeepers, according to the commandment of David and ¹  his son Solomon.

[12:45]  ¹ tc With many medieval Hebrew MSS and the ancient versions the translation reads the conjunction (“and”). It is absent in the Leningrad MS that forms the textual basis for BHS.
