“After him, Baruch son of Zabbai repaired another section from the Angle to the door of the house of the high priest Eliashib. After him Meremoth son of Uriah, son of Hakkoz, repaired another section from the door of the house of Eliashib to the end of the house of Eliashib.”
This is the old wall that started at the west Angle Gate and went due east. A vocal point here was the house of the high priest Eliashib. It must have been an impressive house since one group built up to it while another group repaired right around his house. He also was the one who repaired the Sheep Gate earlier in this chapter. There are other people with the name of Baruch, but this is the only biblical reference to this Baruch. Meremoth also came up earlier in this chapter as he repaired the Fish Gate. He also was a key player in Ezra, chapter 8. Thus we have a connection between the 2 books.
