John Trapp on Proverbs 21:18

Verſ. 18. The wicked ſhall bee a ranſome] Heb. Copher, a cover, or an expiation: as Achan was for Iſrael; and as thoſe condemned perſons among the Heathens,Budaeu[illegible: 1 letter]. that in time of peſtilence or contagious infection, were offered up by way or publick expiation, with theſe words, [non-Latin text not transcribed]. Bee thou a reconciliation for us. To this cuſtome Saint Paul ſeems to allude, 1 Cor. 4.13. Thus, when Sauls ſons were hanged, Gods wrath was appeaſed, 2 Sam. 21. and when guilty Jonah was caſt into the Sea, all was calm. Thus God gave Egypt for Iſraels ranſome: yea Seba and Ethiopia, Iſa. 43.3. And although hee may ſeem ſometimes to ſell his people for nought, and not to encreaſe his wealth by their price, Pſal. 44.12. yet when it comes to a critical point, I will give men for thee, and people for thy price, Iſa. 43.4. See Prov. 11.8. with the Note there.
