After the census the total number of Levites does not tally. How can we reconcile the difference?
Numbers 3:21 (KJV)
21 Of Gershon was the family of the Libnites, and the family of the Shimites: these are the families of the Gershonites. 22 Those that were numbered of them, according to the number of all the males, from a month old and upward, even those that were numbered of them were seven thousand and five hundred.
Numbers 3:27 (KJV)
27 And of Kohath was the family of the Amramites, and the family of the Izeharites, and the family of the Hebronites, and the family of the Uzzielites: these are the families of the Kohathites. 28 In the number of all the males, from a month old and upward, were eight thousand and six hundred, keeping the charge of the sanctuary.
Numbers 3:33 (KJV)
33 Of Merari was the family of the Mahlites, and the family of the Mushites: these are the families of Merari. 34 And those that were numbered of them, according to the number of all the males, from a month old and upward, were six thousand and two hundred.
Numbers 3:39 (KJV)
39 All that were numbered of the Levites, which Moses and Aaron numbered at the commandment of the LORD, throughout their families, all the males from a month old and upward, were twenty and two thousand.
The total number of Levites does not tally with the sub totals given of the Gershonites, Kohathites & Merarites. How can we reconcile the above figures?
