Nehemia 4:12

When, therefore, the Jews who dwelt near them, i.e., in the neighbourhood of the adversaries, and heard their words, came to Jerusalem, "and said to us ten times (i.e., again and again), that from all places ye must return to us, then I placed," etc. Jews came from all places to Jerusalem, and summoned those who were building there to return home, for adversaries were surrounding the community on all sides: Sanballat and the Samaritans on the north, the Ammonites on the east, the Arabians on the south, and the Philistines (Ashdodites) on the west. אשׁר before תּשׁוּבוּ introduces their address, instead of כּי; being thus used, e.g., before longer speeches, Sa1 15:20; Sa2 1:4; and for כּי generally, throughout the later books, in conformity to Aramaean usage. "Return to us" (על שׁוּב, as in Ch2 30:9, for אל שׁוּב), said the Jews who came from all quarters to Jerusalem to their fellow-townsmen, who from Jericho, Gibeon, and Tekoa (comp. Neh 3:2-3, Neh 3:5, Neh 3:7) were working on the wall of Jerusalem. These words express their fear lest those who were left at home, especially the defenceless women, children, and aged men, should be left without protection against the attacks of enemies, if their able-bodied men remained any longer in Jerusalem to take part in the building of the wall. Neh 4:13 Neh 4:7 is hardly intelligible. We translate it: Then I placed at the lowest places behind the wall, at the dried-up places, I (even) placed the people, after their families, with their swords, their spears, and their bows. למּקום מתּחתּיּות is a stronger expression for למּקום מתּחת when used to indicate position, and מן points out the direction. The sense is: at the lowest places from behind the wall. בּצּחחים gives the nature of the places where the people were placed with arms.…

We left all hands at work for the building of the wall about Jerusalem. But such good work is not wont to be carried on without opposition; now here we are told what opposition was given to it, and what methods Nehemiah took to forward the work, notwithstanding that opposition. I. Their enemies reproached and ridiculed their undertaking, but their scoffs they answered with prayers: they heeded them not, but went on with their work notwithstanding (Neh 4:1-6). II. They formed a bloody design against them, to hinder them by force of arms (Neh 4:7, Neh 4:8, Neh 4:10-12). To guard against this Nehemiah prayed (Neh 4:9), set guards (Neh 4:13), and encouraged them to fight (Neh 4:14), by which the design was broken (Neh 4:15), and so the work was carried on with all needful precaution against a surprise (Neh 4:16-23). In all this Nehemiah approved himself a man of great wisdom and courage, as well as great piety.

4:12 They will come from all directions and attack us! Jews from the surrounding areas might have been exhorting the people working in Jerusalem to return to their villages to avoid being killed in an attack.
