Albert Barnes Commentary Isaiah 13:18

"And [their] bows shall dash the young men in pieces; and they shall have no pity on the fruit of the womb; their eye shall not spare children." — Isaiah 13:18 (ASV)

Their bows also - Bows and arrows were the usual weapons of the ancients in war; and the Persians were particularly skilled in their use. According to Xenophon, Cyrus came to Babylon with a great number of archers and slingers (Cyrop. ii. 1).

Shall dash the young men ... - That is, they shall dash the young men to pieces, or kill them by their bows and arrows. Vulgate, And with their arrows shall they slay the young. The meaning of the word here rendered ‘dash to pieces,’ is to smite suddenly to the ground.
