Komentarz do Nehemiasza 3:11

a second measure Just like the measurement which his friend built before [him], so he also built like [his friend.] a second measure in the building of the wall. The expression of measure is inappropriate for the building of the gates because they have [a measure] only in the building of a part of the wall, for we do not find in the entire chapter of the building of the gates the expression of a measure.

the Tower of the Furnaces He also built a tower by that name. All these towers in the chapter were built in the wall around the city.
