And render unto our neighbors - That is, the neighbors who had reproached them; the surrounding people who had seen these calamities come upon them, and who had regarded these calamities as proof that their God was unable to protect them, or that they were suffering under his displeasure. See the notes at Psalms 79:4. “Sevenfold.” Seven times the amount of reproach which they have heaped upon us. The word seven is often used to denote many, as seven was one of the perfect numbers. The idea is that of complete or full vengeance. Compare Genesis 4:15, Genesis 4:24; Proverbs 6:31; Isaiah 30:26; Matthew 18:21-22; Luke 17:4.
Into their bosom ... - Perhaps the allusion here is to the custom of carrying things in the bosom of the flowing dress as it was girded around the loins. “Let them be made to carry with them seven times the amount of reproach which they have endeavored to heap on us.”
