John Gill Commentary Isaiah 13:16

"Their infants also shall be dashed in pieces before their eyes; their houses shall be rifled, and their wives ravished." — Isaiah 13:16 (ASV)

Their children also shall be dashed to pieces before their
eyes
Upon the ground, or against the wall, as was foretold should be, (Psalms 137:8Psalms 137:9) and in way of retaliation for what they did to the Jews, (2 Chronicles 36:17) and this was to be done "before their eyes", in the sight of the inhabitants, which must make it the more distressing and afflicting; and, as Kimchi observes, this phrase is to be applied to the following clauses: their houses shall be spoiled ;
plundered of the substance, wealth, and riches in them, by the Persian soldiers: and their wives ravished ;
by the same, and both before their eyes, and after that slain, in like manner as they had ravished the women in Zion, (Lamentations 5:11) .
