John Lightfoot on John 12:6

[The bag.] We meet with this word in the Greek interpreters, 2 Chronicles 24; and it is set there for a chest or corban box, verse 8: let a purse or bag be made. The Hebrew is, they shall make a chest. So verses 10, 11, &c. Amongst the Talmudists we meet with gloskema [that is the word the Syriac useth in this place], and dloskema. For as the Aruch, gloskema is the same with dloskema, and is a Greek word. It is used commonly for a coffin.

"As Phrynichus writes it, a case of wood to keep relics in; a coffin, a chest, a box, a purse, or rather a coffer (note that) in which they used to lay up their money. It is used, John 12, to signify a purse." And why may it not be read there also for a chest or coffer? for Judas is not said to carry the bag; but that he had the bag, and bare what was put therein. So that nothing hinders but that, even in this place, may signify a chest or coffer of money, fixed at home; the keys of which were in Judas' keeping, and he carried the gifts that were to be put into it.
