John Calvin on Amos 2:5

We now see what sort of crime is that of which the Prophet speaks. At last a threatening follows, “The Lord saith, Fire will I send on Judah, which shall devour the palaces of Jerusalem.’ But all this we have already explained. Let us now proceed —

Amos 2:6

6. Thus saith the LORD; For three transgressions of Israel, and for four, I will not turn away the punishment thereof; because they sold the righteous for silver, and the poor for a pair of shoes;

6. Sic dicit Jehova, Super tribus sceleribus Israel et super quatuor non convertam cum (vel, ad eum,) quia emerunt (vel, vendiderunt: quidam enim deducunt a כרת, et putant מ esse literam formalem nominis: alii autem deducunt a מכר quod est vendere vel mercari; sed sensus Prophetae eodem redit, quia intelligit quasi ad nundinationem expositos fuisse justos; ideoque proestabit vertere, pretium ipsorum; quasi diceret, commercium non secus ac de merce voenale fuisse habitum; quoniam ergo emerunt) justum pro argento, et miserum pro calceamentis.
