by the archers - literally, “by the bow”; so Isa 21:17. Bowmen were the light troops, whose province it was to skirmish in front and (2Ki 6:22) pursue fugitives (2Ki 25:5); this verse applies better to the attack of Nebuchadnezzar than that of Sennacherib.
all ... in thee - all found in the city (Isa 13:15), not merely the “rulers” or generals.
fled from far - those who had fled from distant parts to Jerusalem as a place of safety; rather, fled afar.
