13. Set I in the lower places. The first part of 13 is obscure. It appears that at the more vulnerable points along the wall, where attack was most likely, Nehemiah posted armed men in conspicuous positions in the hope of forestalling an attack. The grouping of men by families would tend to impress upon each of them the fact that he was fighting for his own kin. The enemy may have advanced to positions opposite the “lower,” or more vulnerable, parts of the rapidly rising wall and was feigning preparations to attack when Nehemiah’s prompt action thwarted their plan by making it clear that the Jews were ready to fight if necessary.
