During his remarks, Chief Justice Roberts noted that Magna Carta, singled out the Jews for special treatment concerning repayment of debts and interest.

Here is a translation from Yale:

10. If one who has borrowed from the Jews any sum, great or small, die before that loan be repaid, the debt shall not bear interest while the heir is under age, of whomsoever he may hold; and if the debt fall into our hands, we will not take anything except the principal sum contained in the bond.

11. And if anyone die indebted to the Jews, his wife shall have her dower and pay nothing of that debt; and if any children of the deceased are left under age, necessaries shall be provided for them in keeping with the holding of the deceased; and out of the residue the debt shall be paid, reserving, however, service due to feudal lords; in like manner let it be done touching debts due to others than Jews.

Here is a slightly different translation from Fordham:

(10) If anyone who has borrowed a sum of money from Jews dies before the debt has been repaid, his heir shall pay no interest on the debt for so long as he remains under age, irrespective of whom he holds his lands. If such a debt falls into the hands of the Crown, it will take nothing except the principal sum specified in the bond.

(11) If a man dies owing money to Jews, his wife may have her dower and pay nothing towards the debt from it. If he leaves children that are under age, their needs may also be provided for on a scale appropriate to the size of his holding of lands. The debt is to be paid out of the residue, reserving the service due to his feudal lords. Debts owed to persons other than Jews are to be dealt with similarly.

Some things never change. Even 800 years ago.
