For they all made us afraid
Or you all, as Aben Ezra interprets it; or all the Heathen nations, as Jarchi; this was the design of all those scandalous reports, to intimidate them, and with this they pleased themselves, as follows:
their hands shall be weakened from the work, that it be not done;
this they hoped would be the effect of those reports sent to them:
now, therefore, O God, strengthen my hands;
and let them not have what they will, and hope for; according to Aben Ezra, these words are directed to Sanballat, that if he was a friend, as he pretended, that instead of weakening, he would strengthen his hands by a sincere reconciliation; so Vatablus; but they are an address to God, such short ejaculations being usual with Nehemiah.
