Isaiah 13:15

Every one that is found shall be thrust through; and every one that is joined unto them shall fall by the sword.

Every one that is found - in the city.

Joined, [ hanicpeh (H5595)] - 'intercepted' (Maurer). 'Everyone that has withdrawn himself' [from 'aacap (H622)], namely, to hide in the houses,

Shall fall by the sword (Gesenius). But "add" is the sense of the same Hebrew in Isaiah 30:1, and many passages. Everyone, though not a native, who is joined to Babylon, whether as a trader, a mercenary soldier, or an auxiliary.
