Jeremiah 50:9

He means the Medes and Persians, as it is expounded afterward. Their arrows shall be as of a mighty expert man; none shall return in vain; I will so direct their arrows, that every arrow they shoot shall pierce one or other. Or, (as some raffler choose 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 margin is the difference of a point in the Hebrew, 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.
