Exodus 30:6

Before the mercy-seat that is over the testimony - These words in the original are supposed to be a repetition, by mistake, of the preceding clause; the word הפרכת happarocheth , the veil, being corrupted by interchanging two letters into הכפרת haccapporeth , the mercy-seat; and this, as Dr. Kennicott observes, places the altar of incense before the mercy-seat, and consequently In the holy of holies! Now this could not be, as the altar of incense was attended every day, and the holy of holies entered only once in the year. The five words which appear to be a repetition are wanting in twenty-six of Kennicott's and De Rossi's MSS., and in the Samaritan. The verse reads better without them, and is more consistent with the rest of the account.
