Matthew Poole and continuators on Jeremiah 50:9

9 ¶ For lo, I will raise and cause to come up against Babylon, an assembly of great nations from the north-country, and they shall set themselves in aray against her , from thence she shall be taken: their arrows shall be as of a mighty expert man: none shall return in vain .

He means the Medes and Persian (as it is expounded afterward)

I will so direct their arrows, that every arrow they shoot shall pierce one or another. Or, (as some rather chuse to interpret it) no Soldier of that assembly of great Nations, that shall come up against Babylon shall return without some Booty or other. The reason of the different reading noted in the Margent, is the difference of a point in the Heb. which if set on the right side of the letter, the word signifieth a destroyer: if on the left side, an expert man as we translate it.

Marginal references: Or, destr[illegible: 3 letters].
