And the residue of the number - That is, those who shall be left in the invasion. Or perhaps it may be read, ‘There shall be a renmant of the number of bowmen; the mighty people of Kedar shall be diminished.’
Of archers - Hebrew, ‘Of the bow;’ that is, of those who use bows in war. The bow was the common instrument in hunting and in war among the ancients.
Shall be diminished - Hebrew, ‘Shall be made small;’ they shall be reduced to a very small number. We cannot indeed determine the precise historical event to which this refers, but the whole connection and circumstances seem to make it probable that it referred to the invasion by the Assyrian when he went up against Judah, or when he was on his way to Egypt.
