Exodus 32:28

About, &c. The Hebrew letter c means about, and stands also for twenty. All the versions, and some copies of the Vulgate, retain the first signification; but our edition gives also the second. Sixtus V. and the Louvain Bible have about 33,000. (Haydock) --- St. Paul (1 Corinthians x. 7, 8,) mentions, that three and twenty thousand perished, in punishment of their fornication (with the Moabites), which some explain of the adoration of the calf, and say that Moses only specifies those slain by the Levites; while St. Paul gives the number of all those who perished by the hand of God on this occasion, ver. 35. (Calmet) --- St. Cyril, Alex. glap. 2, Sulpitius, and many other fathers, agree with the Vulgate. The fornication with the Moabites, was followed by the death of 24,000, Numbers xxv. 9. So that St. Paul cannot refer to it, unless he only mention those who perished in one day; and Moses expresses the total amount of the slain during the whole affair. (Haydock)
