John Trapp on Nehemiah 4:10

Verſe 10. And Judah ſaid] Here was [non-Latin text not transcribed], impedimenti domeſtici: aliud ex alio malum, a worſe diſcouragement then the former. Judah (the chief labourers) begins to murmur and mutiny, to faint and fall off. A perillous practiſe in ſuch a dangerous time, and enough to have undone all: as one coward in an army, breaking the array and running away, may ſet the reſt a running, and the day be thereby loſt. Lo, this was Judah, whoſe ſcutcheon was a Lion: but here unlike himſelf.

The ſtrength of the bearers of burdens is decayed] Very ſpecious reaſons: they alledge: their ſhoulders aked, their ſtrength was gone, there was no end of their pains-taking, their work grew upon them, &c. The truth was, deerat ignis, deerat animus, they were weary of well-doing, and not valiant for the truth, Jer. 9.3. More like they were to thoſe fugitives of Ephraim, Judg. 12.4. then the Lions of the Tribe of Judah. Nehemiah therefore might well have ſaid to them as Alexander once did to a faint-hearted ſouldier of his, that was of his own name, Either leave off the name of Alexander, or be valiant. So, either hold out, and bear up under your burdens, or be Judah no more.

So that we are not able] Never was any thing too hard for Alexander; becauſe he never held any thing impoſſible to be effected.
