Nehemia 3:13

3:13 Hanun and the residents of Zanoah worked on the Valley Gate. They rebuilt it and positioned its doors, its bolts, and its bars, in addition to working on fifteen hundred feet ¹  of the wall as far as the Dung Gate.

Nehemia 9:13

9:13 “You came down on Mount Sinai and spoke with them from heaven. You provided them with just judgments, true laws, and good statutes and commandments.

[3:13]  ¹ tn Heb “one thousand cubits.” The standard cubit in the OT is assumed by most authorities to be about eighteen inches (45 cm) long, so this section of the wall would be about fifteen hundred feet (450 m).
