'One' in the Bible

From you [O Nineveh],One has gone forth who plotted evil against the Lord,A malevolent counselor [the king of Assyria].

Though Nineveh was like a pool of water throughout her days,Now her inhabitants are fleeing;“Stop! Stop!” [a few cry,]But no one turns back.

Your guardsmen are like the swarming locusts.Your marshals are like the hordes of grasshoppersSettling in the stone walls on a cold day.When the sun rises, they fly away,And no one knows the place where they are.

Your shepherds are asleep, O king of Assyria;Your nobles are lying down [in death].Your people are scattered on the mountainsAnd there is no one to gather them.
