Charles Ellicott 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 shall dash the young men to pieces. —These, as in Isaiah 22:6, Jeremiah 1:9–14, were the characteristic weapons of the Medo-Persian armies.
